As the clock winds down to Dec. 21, experts on the Maya calendar have been racing to convince people that the Mayas didn't predict an apocalypse for the end of this year.

Some experts are now saying the Mayas may indeed have made prophecies, just not about the end of the world.

Archaeologists, anthropologists and other experts met in the southern Mexico city of Merida to discuss the implications of the Maya Long Count calendar, which is made up of 394-year periods called baktuns.

Experts estimate the system starts counting at 3114 B.C., and will have run through 13 baktuns, or 5,125 years, around Dec. 21. Experts say 13 was a significant number for the Mayas, and the end of that cycle would be a milestone — but not an end.

Fears that the calendar does point to the end have circulated in recent years. People in that camp believe the Maya may have been privy to impending astronomical disasters that would coincide with 2012, ranging from explosive storms on the surface of the sun that could knock out power grids to a galactic alignment that could trigger a reversal in Earth's magnetic field.

Mexican government archaeologist Alfredo Barrera says that the Mayas did prophesize, but perhaps about more humdrum events like droughts or disease outbreaks.

"The Mayas did make prophecies, but not in a fatalistic sense, but rather about events that, in their cyclical conception of history, could be repeated in the future," says Barrera, of the National Institute of Anthropology and History.

Experts stressed that the ancient Mayas, whose "classic" culture of writing, astronomy and temple complexes flourished from A.D. 300 to 900, were extremely interested in future events, far beyond Dec. 21.

"There are many ancient Maya monuments that discuss events far into the future from now," writes Geoffrey Braswell, an anthropologist at the Univ. of California, San Diego. "The ancient Maya clearly believed things would happen far into the future from now."

"The king of Palenque, K'inich Hanaab Pakal, believed he would return to the Earth a couple of thousand years from now in the future," Braswell writes in an email to The Associated Press. "Moreover, other monuments discuss events even before the creation in 3114 B.C."

Only a couple of references to the 2012 date equivalency have been found carved in stone at Maya sites, and neither refers to an apocalypse, experts say.

Such apocalyptic visions have been common for more than 1,000 years in Western, Christian thinking, and are not native to Maya thought.

"This is thinking that, in truth, has nothing to do with Maya culture," says Alexander Voss, an anthropologist at the Univ. Of Quintana Roo, a state on Mexico's Caribbean coast. "This thing about looking for end-times is not something that comes from Maya culture."

Braswell compared the Maya calendar, with its system of cycles within cycles, to the series of synchronized wheels contained in old, analogue car odometers.

"The Maya long count system is like a car odometer," Braswell wrote. "My first car (odometer) only had six wheels so it went up to 99,999.9 miles. That didn't mean the car would explode after reaching 100,000 miles."
