Camera crews from all over the world continue to work Friday beyond 11:11 a.m., the time the Mayan apocalypse was supposed to occur in Bugarach village, France.

BUGARACH, France — The peacefulness of the Sals River Valley at the foothills of the Pyrenees in France belies its violent, enigmatic history. Once the place of ancient marauding Visigoths, its small villages were also home to the mystical Cathars and to the protectors of the cloth, the Knights Templar – both eliminated by inquisitions and despotic rulers.

Roughly two years ago, the peace of this land was broken once again by strange rumors surfacing online about Bugarach Mountain, a rocky beacon presiding over the landscape.

According to some reports, the peak of the mountain conceals an alien spaceship. Other sources say it is part of an alien space-time portal. The origins of the UFO stories have been difficult to trace, but have generated a response bordering on hysteria. Under normal circumstances, probably, such bizarre claims would have slunk away unnoticed or been relegated to the crazy bin. But, as they say, timing is everything.

For years, doomsayers warned that the end of a 5,125-year cycle in the Maya timekeeping system, which culminated on Dec. 21, would also signify the end of the world. In recent months, the UFO story has taken over the public imagination. Instead of being passed off as nonsense, Bugarach and its "resident UFO" became star European players in a global doomsday pantomime. And when it was announced that the regional authorities were calling in police and paramilitaries to prevent cultists from ascending the peak on doomsday, the village became the center of a media storm — a different kind of pantomime altogether.

Driving into the village on the morning of Dec. 19, a number of elements met the eyes: telltale blue uniforms and police vans peppering the sides of the roads, smoke rising languidly from stone chimneys, the looming figure of Bugarach Mountain. Other sights included columns of SUVs and satellite trucks snaking their way along the country roads. Roving packs of groomed-yet-rugged types with press passes and hungry looks were busy claiming positions within cordoned-off areas in the village.

No sight of cultists, or for that matter, anything more otherworldly than a mass of waterproof jackets and the hardened boots of teams waiting for their scoop. Soggy fields bordered with caution tape were reserved for vehicles, and over the course of the day the fields became emblazoned with acronyms and company crests, resembling an army of knights from different royal houses, awaiting battle.

Optimism reigned for the two days leading up to the eschatological event. Reporters heartily greeted each other and rival camera crews were sportingly scoped out. At dinner, the catch phrase, "Where are you from?" echoed around as different teams sat side by side at long tables, rubbing elbows and even sharing a bit of rustic bread. A cacophony of tongues filled the room. Outside, the village remained strangely empty.

Dawn breaks on Dec. 21 in Bugarach. Where are all the hippies? A Dutch producer mutters: "Maybe they’ve already crossed through the star gate." Most likely, they’ve been chased away.

"Anyway, who the heck would want to ride to another planet with this bunch?" NBC News overhears a French cameraman saying to his sound technician as he looks around the square.

An unidentified woman speaks to journalists in the village of Bugarach in southern France on Dec. 21.

The few locals venturing out in the open are either bemused and vague, or are capitalizing on all the attention to make some cash — steaming croissants and chai tea are sold at a makeshift stall. The clientele? Dutch, French and Japanese TV crews. A young video artist from Switzerland takes a photo of a photographer taking a photo of reporters.

"This is very postmodern," he laughs. "This is the new story."

From time to time, rogue civilians break the fatigue that's setting in. A man arrives carrying a placard with the words, "The black stone of Bugarach." In an instant, he is mobbed by TV crews. Later, an angry resident shouts at the throng. Lenses swing and snap wildly.

Author Henry Lincoln accuses the media of creating and hyping the story.

"You’re doing it," he told NBC News. "If you would leave us in peace, nobody would be yelling about the end of the world and flying saucers coming to Bugarach."

Fair enough, this once sleepy town has been invaded. Neither by UFOs nor by extremists of any sort, but rather by dogged pursuers of what has proven to be an elusive story.

At what point does a reporter abandon a story? "Let’s get out of here. This is embarrassing," a correspondent states flatly.

Almost reluctantly, engines begin to start.

A tourist raises her hands during a group meditation ceremony near the pyramid of Kukulkan at the Chichen Itza archaeological site on Dec. 21. Hundreds gathered to greet the sunrise on a day that marked a new age on the Maya calendar.

Tourists, mystics and Maya priests accentuated the positive this morning at Mexico's best-known Maya monument, the El Castillo pyramid at Chichen Itza, on a day that some thought would bring catastrophe.

For years, doomsayers warned that the end of a grand 5,125-year cycle in the Maya timekeeping system would signify the end of the world as well. Some feared that Dec. 21 would be marked by solar blasts, earthquakes, superstorms or other planetary disruptions. But the hundreds who flocked to El Castillo took a different message to heart.

"It's not the end of the world, it's an awakening of consciousness and good and love and spirituality — and it's been happening for a while," Mary Lou Anderson, a 53-year-old information technology consultant from Las Vegas, told Reuters.

Reuters reported that the rituals at Chichen Itza began just before the winter solstice, as dawn was breaking. A spotlight illuminated the western flank of El Castillo, a 100-foot-high pyramid that was built sometime between the 9th and the 12th centuries to serve as a temple to the Maya serpent god Kukulkan. Then a group of five English-speaking tourists, dressed in white,  made their way across the plain, dropped their bags and faced the pyramid with their arms raised. 

As the sun climbed into the sky, a man with dreadlocks played a didgeridoo at the north end of the pyramid, while a group of tourists meditated on brightly colored mats.

The visitors said they came to Chichen Itza not to face the world's end, but to make a new beginning. "I hope something happens to make me a better person," said Graham Hohlfelde, a 21-year-old student from St. Louis, Mo. "If I can get a little cosmic help, I won't turn it down."

Two men dressed in tinfoil stand in the French village of Bugarach on Friday. The mountain near Bugarach was touted as a haven from the Maya apocalypse, but most of those who came to the village on the big day were journalists.

Doomsday was a bust in the French village of Bugarach, which was supposed to be one of the rare safe havens during the Maya apocalypse.

In advance of today's supposed global crisis, rumor-mongers spread the word that a peak near the picturesque village in the French Pyrenees (population: 200) would be the only place on Earth to escape destruction. A giant UFO and aliens were said to be waiting under the mountain, ready to burst through and spirit those nearby to safety.

When the rumors cropped up, authorities worried that tens of thousands of New Agers would overwhelm the village — so French gendarmes tried to seal off access to anyone not having the proper papers.

Some believers made it through. Ludovic Broquet, a 30-year-old plumber, told The Associated Press that he put a year of preparation into his trek, in hopes of finding a "gateway, the vortex that will open up here (at) the end of the world."

But most of the visitors to Bugarach today were journalists. The Telegraph's Henry Samuel was among the throng looking for action in the village. He found two brothers from Marseille who spent the night in a cave on the mountainside waiting for the vortex to open.

Although they never found the vortex, they did report seeing a bluish light in the cave in the middle of the night.  "It stopped, started to look at us, and rushed towards us," one of the brothers, identified as Laurent, told The Telegraph. "I had a feeling of ecstasy. It’s hard to describe. We had our fair dose and are on our way out."

People gather in the French village of Bugarach on Friday while authorities block access to a nearby mountain.

The journalists are on their way out, too, leaving behind some miffed villagers. "What is going on here is the creation of an urban legend," Michele Pous told AP.

Pous blamed the folks who started the rumors: "They created a media frenzy, they created a false event, they manipulated people."

This morning's report on TODAY recaps the no-show for the apocalypse, and the segment raises an interesting question: What about all those folks who were preparing for the sort of doomsday portrayed in the movie "2012"?

"Doomsday Preppers" is the top-rated show on the National Geographic Channel, and the show will stay on the air even though the Maya apocalypse was canceled. I'm betting that the preppers will keep prepping as well. In fact, the devastation caused by Superstorm Sandy demonstrates that it's wise to stock up on emergency gear and extra supplies even if you see absolutely no deeper meaning in a centuries-old calendar.

Most of the people concerned about the end times are not motivated by the Maya myth, but rather by biblical reference to the end times — or just a general sense that things are going to go south sometime soon. That came through clearly when Zap2it's Jacqueline Cutter chatted with some of the National Geographic Channel's preppers.

Braxton Southwick, a mechanic living in a Salt Lake City suburb, told Cutter that he was inspired by the 9/11 crisis.

"I don't want to see my kids go though horrible crap or gangs or starve," he says. "If you were told you were going to be in a concentration camp, you would say 'I am going to die.' But they fought to live. So I look at it that way. Human nature is to fight to live."

Do you know of anyone who's making preparations for a future doomsday? Are you a doomsday prepper yourself? Feel free to get your point across in the comment section below.

Guatemalan Mayan natives take part in celebrations marking the end of the Maya age at the Tikal archaeological site on Friday.

The sun has arisen today at Maya monuments in Mexico and Guatemala, heralding the completion of a 144,000-day calendar cycle — but not the end of the world.

Most archaeologists say the ancient Maya regarded sunrise as the signal for the turnover, much as we regard midnight on New Year's Eve as the time to party. And sure enough, tourists as well as modern-day Maya in traditional garb gathered at Chichen Itza's El Castillo pyramid in Mexico to greet the day. Josh Gates, host of the Syfy TV show "Destination Truth," is live-tweeting the activities. (Syfy is owned by NBC Universal, which also owns NBC News Digital.)

The ancient Maya calendar marks Dec. 21 as the end of a cycle known as a baktun, which lasts 144,000 days or nearly 400 years. This finishes up the 13th baktun since Year Zero for the Maya, and taken together, all that time represents an even longer 5,125-year cycle of creation. That led to speculation that the Maya expected the gods to reset the cosmos on Dec. 21. Somehow that speculation was taken seriously enough to whip up this whole end-of-the-world hype.

Along the way, all sorts of claims were made about unseen planets, solar disturbances and other supposed earth changes that would make today a very bad day. But judging from the pictures coming from Chichen Itza and other Maya monuments, people are having a good time today.

In the longer term, Maya community leaders hope all the attention they're getting this week will translate into a wider awareness of their ancient culture and their modern-day challenges. They're not worried about doomsday; they're worried about poverty. Check out this PhotoBlog posting for more about the real concerns being voiced by the indigenous people of Guatemala.

During the buildup to 12/21/12, some people added an extra solstice twist to the Maya doomsday myth, contending that the precise time of the end of the world would be 11:11 UTC, or 6:11 a.m. ET. That's because the turnover date of the Maya Long Count calendar also happens to be the date of the December solstice, when winter starts in the Northern Hemisphere and summer begins in the Southern Hemisphere. Well, the solstice has occurred, and we're all still here.

What good is an apocalypse without a Twitter account? Mayan Apocalypse (@kabooooooooom)  has just chimed in with its first tweet: "Sorry everyone, running a bit late."

After years of claptrap about the Maya apocalypse on 12/21/12, the Big Day has dawned in many parts of the world. It's daytime in China, one of the world's hot spots for doomsday angst. So far, no solar flares have fried the earth, and no mountains have fallen into the sea. The sun will soon rise on Mexico's ancient Maya monuments, where thousands are gathering to greet a new era.

Then what?

"I don't think there's going to be a herd of jaguars descending from the heavens," said John Henderson, an anthropologist at Cornell University who specializes in the Maya world.

Archaeologists and astronomers have thoroughly debunked everything about the doomsday myth: The Maya never expected that the world would end when their Long Count calendar rolled over to the next 144,000-day cycle in 2012. Earth's magnetic field is not going haywire. There's no threat from the Large Hadron Collider, or the sun, or unseen planets, or the galactic plane.

Not everything about the Big Day is doom and gloom: Tourists and New Age types have flocked to the Maya ruins of Chichen Itza to greet Friday's dawn and the start of a new age with rituals old and new. "There is an explosion of consciousness through this," a gray-haired Californian musician named Shambala Songstar told Reuters. "We are becoming billionaires of energy. Opening to receive more light and more joy."

Minu Nair, a 27-year-old tourist from India, joked about the doomsday connection after hiking up to the top of the Maya pyramid at Coba, about an hour's drive from Chichen Itza. "At least we can die saying we saw the end of the world," he said with a laugh.

But not everything is sweetness and light, either. "We have to beware of mass psychosis," said Mexico's best-known soothsayer, Antonio Vazquez Alba. According to The Associated Press, Vazquez warned his followers to stay away from mass gatherings on Friday, out of concern about stampedes — or even mass suicides "of the kind we’ve seen before."

Guatemalan shaman Christian Nottbohn conducts a Maya ceremony in Rastrajon, which was once a settlement for warriors tasked with protecting the ancient city of Copan in present-day Honduras.

Elsewhere, more than 1,000 members of Church of Almighty God were reportedly detained in China for spreading doomsday rumors. Hundreds more were heading for Serbia's Mount Rtanj and the French town of Bugarach, in search of a haven from the apocalypse. Authorities in Argentina limited access to a mountain called Cerro Uritorco after rumors spread about a plan for "massive spiritual suicide." In Michigan, dozens of schools were shut down early, partly because of end-of-the-world worries stoked by the Maya hype.

What would the ancient Maya think? "The Maya thought about everything in terms of cycles," Henderson told NBC News today. "Some may have expected the gods to fine-tune their creation of humanity. But others may have taken it more as an occasion to contemplate whether they were the kind of people they ought to be. And we can take it in the same way."

Think of it as the opportunity for New Year's Resolutions — or, in this case, New Baktun's Resolutions.

The Maya Long Count calendar divides time into a series of periods, building up to a cycle called the baktun that lasts 144,000 days, or a little more than 394 years. Dec. 21 marks the completion of 13 baktuns, which the Maya saw as a full cycle of creation. In some texts, the end of the 13th baktun — 13.0.0.0.0, in numerical notation — was used to refer to a long, long time.

"It would be like you and I saying, 'George Washington was such a great leader for us that we'll still be talking about him in the year 3000,'" said Walter Witschey, an anthropologist and Maya expert at Longwood University in Virginia.

But the Maya never thought time stopped in 2012 — or the year 3000, for that matter. A recently discovered Maya workshop demonstrated that calendar-makers contemplated time frames well beyond 2012, and the longest Maya calendar cycle, the alautun, goes out about 63 million years.

More: How the Maya calendar works

The concept of a Maya apocalypse appears to date to the 1960s: That was when anthropologist Michael Coe wrote a book speculating that the Maya saw the final day of the 13th baktun as the time for an "Armageddon" that would overtake all creation. Over the years, that idea became wrapped up with Christian ideas about the end times.

"So much of this Maya calendar fascination plays to very natural human tendencies to look for sources of information about the future, right?" said Loa Traxler, an archaeologist who is the curator of a "Maya 2012" exhibit at the Penn Museum in Philadelphia. "When you add to that a lot of opinions that would point us to the end of days, and events of great reckoning, and destruction as the opening chapter of great change ... those are trends that play very strongly in modern society."

Some cultures get more concerned about it than others. In May, an international public opinion survey conducted by Ipsos for Reuters found that 20 percent of the Chinese respondents agreed that the Maya calendar would mark the end of the world. About 12 percent of the U.S. respondents felt that way, compared with only 4 percent in Germany.

Traxler said she encountered several well-educated people who asked her serious questions about the 2012 Maya apocalypse during a cruise through the Mediterranean in 2009. "It caught me by surprise," she said.

Her experience on that cruise was one of the reasons why she went to work on the "Maya 2012" exhibit, which tells the full story about the ancient Maya and their attentiveness to the cycles of time. "It has been quite an amazing adventure over the last several months," she said. "People have decided to make hay out of this."

So when exactly does it stop? The consensus view among archaeologists is that the 13th baktun will end, and the 14th will begin, at sunrise Friday. "That would be sunrise in the Maya world, not in Beijing," Henderson joked.

But Witschey said there's still a bit of uncertainty about how the dates are calculated. "Most scholars would agree that we have a match within about three or four days," he said. "That means that the rollover of cycle 13 is going to hit on Dec. 21, or 23, or 24."

If past doomsday scares are any guide, it will take a while for the folks who were so worried about 12/21/12 to settle down. Some might claim that the date for the apocalypse was miscalculated, and will actually come at a later time. Others might say that the world-shifting change has actually begun, but the rest of us just can't sense it yet. Case studies abound, ranging from the Great Disappointment of 1844 to the Planet Clarion prophecy of 1954 to the Rapture of 2011.

The precise day or hour of the Maya calendar turnover doesn't matter all that much to Witschey.

"It's no big deal," he said. "Whatever day it is, I'm going to wake up the next day, going forward."

That sounds sensible to me. How's it sound to you? Even though it's no big deal, we'll be passing along updates during the Big Day and beyond. Just check in with http://cosmiclog.nbcnews.com/2012 for the latest.

Update for 9:15 p.m. ET: Although New Zealand hasn't had to contend with a Maya apocalypse, they might have to deal with the remnants of Cyclone Evan over the long weekend.

Update for 11:15 p.m. ET: NASA says it has been fielding hundreds of questions a day from people who are worried about 12/21/12. "We have done all we can to answer questions from the public," David Morrison, an astrobiologist at NASA's Ames Research Center, told NBC News in an email. "Unfortunately, many don't believe us, like several mothers who have written to me in the last few hours asking if they should keep their children at home today."

Morrison forwarded one email message (with the sender's name removed) that he said was typical. Here's what it said: "Just like to know how I can survive the end of the world? Two friends of mine committed suicide this week because of that dreaded day, date. I just want to try to survive, and please tell me what to do!?"

It's impossible to verify the substance of that particular email, but if the sentiment is "typical," I'm hoping such folks are getting the reassurance they need. DON'T PANIC!

Update for 9:20 a.m. ET Dec. 21: I've added a video from TODAY that sounds the all-clear in the apocalypse drill.

NASA's latest video debunking doomsday hype comes from the future — to be precise, from Dec. 22, one day after the expected peak for worries that the end of an ancient Maya calendar cycle will signal the end of the world as well. Some might think that the video, titled "The World Didn't End Yesterday," was prematurely released. But it wasn't: The advance word about the non-apocalypse is a key part of the space agency's plan.

"The teaser for the video explains everything: 'NASA is so confident that the world is not coming to an end on Dec. 21, that they have already released a video for the day after,'" Tony Phillips, the writer and editor behind the NASA Science website as well as SpaceWeather.com, told NBC News in an email.

Phillips says the "day after" angle was his idea.

"I felt it was a lighter and more creative way to approach the topic than some of the other treatments we've seen," he wrote. "Some people have been confused by it, but not all. The unorthodox approach is definitely a conversation-starter, which was our goal all along."

Bashing the bunkum
As the 12-21-12 date approaches, NASA has been taking the lead in telling people that the connection between the Maya calendar and doomsday fears is pure bunkum. By some accounts, a grand 5,125-year cycle comes to an end on Dec. 21, but this year, archaeologists found that the Maya calendar counting system goes beyond 2012, just as our own calendar recycles itself after Dec. 31. For what it's worth, there's even some question whether Dec. 21 is the right date for the Maya calendar turnover.

INAH

The Maya "Long Count" calendar and its connection to 2012 has long been a topic of controversy.

Along the way, the Maya hype has gotten mixed up with other end-of-the-world memes, ranging from monster solar storms to the onset of a threatening Planet X. There's a germ of truth behind some of the memes. For example, the sun really is heading toward the peak of its 11-year activity cycle, but solar maximum won't cause the end of the world. In fact, Phillips has said the upcoming solar max could be "the weakest of the Space Age." Meanwhile, our planet is indeed heading toward a rough alignment with the sun and the galactic center on Dec. 21 — but that alignment happens every year at this time, due to the winter solstice.

NASA has been spending a lot of time lately separating the scientific fact from the scary fiction. Last month, the space agency put together a Web page that addresses the frequently asked questions about the 2012 hype, with links to even more information about topics ranging from polar shifts to supernovae and super volcanoes. This may sound like overkill, but it's not: Earlier this year, an international opinion survey conducted by Ipsos for Reuters found that 14 percent of the respondents believe the world will come to an end during their lifetime — and 10 percent said they were worried that the Maya calendar change-over would mark the end of the world.

What to tell your kids
All this doomsday hype can be particularly troubling for kids, who tend to look to the grown-ups for a reality check. Do your children need some reassurance? These tips from Kids.gov, the U.S. government's Web portal for the younger set, could come in handy:

• Take their fears seriously. Dismissing a fear with a quick "don't be silly comment" or brushing it aside by telling them not to worry is not going to help. If your children express a fear, take time to sit down and discuss it. This sends the message that you are really listening and that your kids can always come to you and they will be taken seriously.
• Educate yourself about the topic of their fears. This allows you to speak confidently about the subject and give you the facts when discussing a rumor.
• Help your child research the rumor. If your child heard the rumor at school or saw something scary on the Internet, sit down with him at the computer and help him to conduct his own research. Discuss the importance of finding credible sources for information and guide him to legitimate, authoritative resources.
• Take the fear off their plate. For younger children, sit down to discuss the child's fear and then tell them, "OK, from now on I will worry about this for you. You don’t have to worry about this anymore. I’ll look into it and I will let you know what I find out." Make sure to check back with your child once you have researched the topic.

Boston University archaeologist William Saturno carefully uncovers art and writings left by the Maya some 1,200 years ago. The art and other symbols on the walls may have been records kept by a scribe, Saturno theorizes. Saturno's excavation and documentation of the house were supported by the National Geographic Society.

Archaeologists have found a stunning array of 1,200-year-old Maya paintings in a room that appears to have been a workshop for calendar scribes and priests, with numerical markings on the wall that denote intervals of time well beyond the controversial cycle that runs out this December.

For years, prophets of doom have been saying that we're in for an apocalypse on Dec. 21, 2012, because that marks the end of the Maya "Long Count" calendar, which was based on a cycle of 13 intervals known as "baktuns," each lasting 144,000 days. But the researchers behind the latest find, detailed in the journal Science and an upcoming issue of National Geographic, say the writing on the wall runs counter to that bogus belief.

"It's very clear that the 2012 date, this end of 13 baktuns, while important, was turning the page," David Stuart, an expert on Maya hieroglyphs at the University of Texas at Austin, told reporters today. "Baktun 14 was going to be coming, and Baktun 15 and Baktun 16. ... The Maya calendar is going to keep going, and keep going for billions, trillions, octillions of years into the future."

The current focus of the research project, led by Boston University's William Saturno, is a 6-by-6-foot room situated beneath a mound at the Xultun archaeological site in Guatemala's Peten region. Maxwell Chamberlain, a BU student participating in the excavations there, happened to notice a poorly preserved wall protruding from a trench that was previously dug by looters, with the hints of a painting on the plaster.

Saturno said he didn't think there'd be much to the wall, but "I felt we had a responsibility to find out at the very least how large this room was."

When archaeologists worked their way into the mound, they were amazed to find that it was a richly decorated room from the Classic Maya period, dating back to roughly the year 800. One niche was adorned with the faded picture of a Maya king, wearing a blue-feathered headdress and holding a white scepter. The picture of a scribe holding a stylus, perhaps the son or brother of the king, was painted nearby with the label "Younger Brother Obsidian." Another wall showed a row of three stylized black figures, with one bearing the hieroglyphic name "Older Brother Obsidian."

The painted figure of a man — possibly a scribe who once lived in the house built by the ancient Maya — is illuminated through a doorway to the dwelling, in northeastern Guatemala. The structure represents the first Maya house found to contain artwork on its walls. The research is supported by the National Geographic Society.

Never-before-seen artwork — the first to be found on walls of a Maya house — adorn the dwelling in the ruined city of Xultún. The figure at left is one of three men on the house's west wall who are painted in black and wear identical costumes. One of the black figures is named "Older Brother Obsidian." The figure in the center appears to be a scribe, labeled "Younger Brother Obsidian." A Maya king is portrayed at far right. Heather Hurst rendered the paintings in clearer detail below.

A vibrant orange figure, kneeling in front of the king on the ruined house's north wall, is labeled "Younger Brother Obsidian," a curious title seldom seen in Maya text. The man is holding a writing instrument, which may indicate he was a scribe. The painting re-creates the design and colors of the figure in the original Maya mural.

Three male figures, seated and painted in black, appear in a painting that re-creates the design and colors of a Mural found on the ruined house's west wall. The men wear only white loincloths and medallions around their necks, plus a headdress bearing another medallion and a single feather. One of the figures is particularly burly and is labeled "Older Brother Obsidian." Another is labeled as a youth.

A Maya king, seated and wearing an elaborate headdress of blue feathers, adorns the north wall of the ruined house discovered at the Maya site of Xultun. An attendant, at right, leans out from behind the king's headdress. The painting by artist Heather Hurst re-creates the design and colors of the original Maya artwork at the site.

Rows of numbers and hieroglyphs were painted on yet another wall. In fact, it appeared that the wall had been plastered over repeatedly and covered with new sets of figures. "What these are giving us are time spans," Stuart said. "Not so much dates, but Maya notations of elapsed time."

Stuart said some sets of numbers denoted lunar cycles of 177 or 178 days, along with the sign for a patron god that was associated with each cycle. "This was, we think, a calculator for a Maya priest, an astronomer, to figure out lunar ages," he said.

In a news release, Saturno said this represents the first look at "what may be actual records kept by a scribe, whose job was to be official record keeper of a Maya community."

"It's like an episode of TV's 'Big Bang Theory,' a geek math problem and they're painting it on the wall," Saturno said. "They seem to be using it like a blackboard."

In addition to lunar cycles, the calculations on the wall could relate to the periods of Venus, Mercury and Mars, the researchers reported. Stuart said such calculations could have come into play for predicting eclipses. He imagined that there might be "one or more, maybe two or three of these astronomers or calendar priests working, sitting there on a workbench and writing these notations on the wall."

One array of numbers would be particularly intriguing to doomsday debunkers: lists that appear to denote wide ranges of accumulated time, including a 17-baktun period. "There was a lot more to the Maya calendar than just 13 baktuns," Stuart observed. Seventeen baktuns would stand for about 6,700 years, which is much longer than the 13-baktun cycle of 5,125 years. However, Stuart cautioned that the time notation shouldn't be read as specifying a date that's farther in the future than Dec. 21.

"It may just be that this is a mathematical number that they find interesting, kind of floating in time," he told me. "But it certainly is expressing a capacity of time. If they were calculating something from their time period, around 800 A.D., yeah, this would have gone way beyond 2012. But again, we're not sure exactly what the base of the calculation is."

Four long numbers on the north wall of the ruined house relate to the Maya calendar and computations about the moon, sun and possibly Venus and Mars; the dates may stretch some 7,000 years into the future. These are the first calculations Maya archaeologists have found that seem to tabulate all of these cycles in this way. Although they all involve common multiples of key calendrical and astronomical cycles, the exact significance of these spans of time is not known.

Saturno said archaeologists have been trying to get out the word that the end of the Maya culture's 13-baktun "Long Count" calendar didn't signify the end of the world, but merely a turnover to the next cycle in a potentially infinite series — like going from Dec. 31 to Jan. 1 on a modern calendar, or turning the odometer on a car over from 99999.9 to 00000.0.

"If someone is a hard-core believer that the world is going to end in 2012, no painting is going to convince them otherwise," he said. "The only thing that can convince them otherwise is waiting until Dec. 22, 2012 — which fortunately for all of us isn't that far away."

Saturno and his colleagues plan to be studying the Xultun site long after that time. He said the workshop was apparently part of a residential compound that had been razed over the ages; the workshop was preserved because it was filled in with material rather than smashed down from above. That could suggest that the room was recognized as a special place even when it was abandoned. Research into the room and its purpose is continuing, Saturno said.

In its day, Xultun apparently served as one of the major ceremonial cities for the Classic Maya civilization — and yet it's just barely been explored, in part because the area is so remote.

"We have probably 99.9 percent of Xultun left to explore," Saturno said. "We're going to be working on it probably for many decades to come. ... Four or five years in to the research project, we have yet to determine its actual boundaries — so my estimate may be off. We may have 99.99 percent left to excavate."

INAH

The Maya Long Count calendar and its connection to 2012 have long been topics of controversy.

What is it about doomsday that draws a crowd?

Time after time, doomsayers have predicted the breakdown of society on a date certain, stirring up a buzz that builds to a crescendo and ends in a crash when doomsday doesn't come. 1844 brought the Great Disappointment, 1999 brought the Y2K alarm, 2011 brought the Rapture ruckus, and exactly a year from today, we're due for the Maya apocalypse.

If the past is any indicator, we'll be intently blogging, tweeting and indulging in black humor as the clock ticks down to Dec. 21, 2012. Then, on Dec. 22, we'll look around for the next doomsday.

It's just human nature, says Oregon State University sociologist Richard Mitchell, author of a book about survivalist trends titled "Dancing at Armageddon." Telling stories and trading tips for making it through the catastrophe that's ahead of us are pursuits that go back to ancient times.

"The attraction of all of these 'final crisis' tales is in the re-narration, the puzzling out of the details, the putting of fragmented facts into a coherent narrative," Mitchell said.

There are plenty of fragmented facts to choose from for 2012's "end of the world" narrative, including the Maya Long Count calendar, which supposedly winds down to the end of a 5,126-year-long cycle next Dec. 21. Today the city of Tapachula in southern Mexico is turning on a digital clock for the yearlong countdown, and Mayan priests are performing a ceremony at a nearby archaeological site.

They're dramatizing the doomsday date largely to drum up tourism. "If people are interested, we have to take advantage of this," Manolo Alfonso Pino, the regional tourism director for Mexico's Chiapas state, told The Associated Press.

Other angles include the recent string of natural disasters and extreme weather events, the upswing in solar activity, and even the ramp-up of the Large Hadron Collider. The narrative gets embellished with additional twists from seemingly ancient lore, such as the feared approach of a mysterious unseen planet, or a prediction that "30 hours of blindness" will beset us.

Some of the concerns should be taken seriously — for example, heightened solar storms really can have a negative effect on power grids and communication satellites, and the link between global warming and wild weather is truly a valid topic of scientific debate. But there's no need to worry about Planet X or the LHC, and even the real concerns aren't any cause for catastrophic talk. Don Yeomans, who heads the Near Earth Object Program at NASA's Jet Propulsion Laboratory, addresses the 2012 hype in this video:

Mitchell doesn't expect the hard-core prophets of doom to accept the assurances of NASA ... or, for that matter, Cosmic Log. "They don't trust the media or academia, because we do in fact pose a real threat — not to their physical well-being, but to their storytelling," he said.

Any potential for panic?
Is there a danger in doomsday stories? Based on his studies of survivalists, Mitchell doubts that 2012 worries will touch off mass panic. He told me that folks who are worried about the collapse of society usually shy away from group activities. "There aren't any 'groups,' though one will pop up every once in a while, just to see and be seen," he said. "It's just a myth to suggest that groups exist, other than online mailing lists that nudge electrons back and forth. Largely, it's individual activity, if there's any activity at all."

But Rosanna Guadagno, a social psychologist at the University of Alabama, worries that websites and apocalyptic chatter on the Internet could create a "tipping point" for 2012 hysteria. "I think it's going to ramp up as we get closer to next December," she told me.

Guadagno's research focuses on the effect that computer-mediated communication has on social interaction and influence.

"The one thing that we have going against us is the way that information spreads online," she told me on Tuesday. "For example, yesterday half the world thought Jon Bon Jovi was dead, just because one person set up a website."

What if someone decided to go viral with the apocalypse?

"It won't take that many people to take advantage of the Internet, to basically spread a lot of misinformation and cause panic among greater numbers," Guadagno said. "Hopefully the general public will be forewarned that this is all bunk."

That's what we're here for. And we'll be here whenever the bunk hits the fan during 2012. So whatever you do, DON'T PANIC!

Update for 5 p.m. ET: The doomsday predictions have centered on Dec. 21 as the fateful date, but that's not the unanimous opinion of experts on Maya glyphs. Penn Museum's Simon Martin, for example, is among those who say that Dec. 23 rather than Dec. 21 marks the end of the Maya calendar's millennia-long baktun cycle. Actually, the discrepancy may turn out to be more than just a couple of days: Gerardo Aldana, a professor at the University of California at Santa Barbara, says conversions of the Maya calendar to the modern calendar could be off by as much as 50 to 100 years.

An exhibit at the Penn Museum, titled "Maya 2012: Lords of Time," will focus on the ancient Maya people's conceptions of the universe, including their ideas about time and the calendar. The Philadelphia show opens on May 5 and will end on ... Jan. 13, 2013. 

Extra credit: After 2012, what's the next doomsday to watch for? Here are a few dates that are popping up:

• 2014, when the LHC is due to reach full power. Some folks believe the second decade of any century is a rough time, just because it historically has been. Nicholas Boyle, a professor specializing in German literature and history at Cambridge University (and no close relative of mine), has already written a book on that theme titled "2014: How to Survive the Next World Crisis." Not sure what that has to do with German, but OK. 
• 2029, when futurist Ray Kurzweil expects machine intelligence to equal human intelligence.
• 2045, when Kurzweil foresees a global transformation dramatic enough to be classified as a "singularity."
• 2060, the "no-earlier-than" date for Isaac Newton's predicted doomsday.

It's interesting that these dates are all about 15 years apart. Is there a 15-year doomsday activity cycle, analogous to the 11-year solar activity cycle? That's one more thing to mull over in the comment section below.
