drop, pop, kaboom !

Just as "Y2K" and its batch of predictions about the year 2000 have become a distant memory, here comes "Twenty-twelve."

Fueled by a crop of books, Web sites with countdown clocks, and claims about ancient timekeepers, interest is growing in what some see as the dawn of a new era, and others as an expiration date for Earth: December 21, 2012.

The date marks the end of a 5,126-year cycle on the Long Count calendar developed by the Maya, the ancient civilization known for its advanced understanding of astronomy and for the great cities it left behind in Mexico and Central America.

The hype also has mainstream Maya scholars shaking their heads.

"There is no serious scholar who puts any stock in the idea that the Maya said anything meaningful about 2012."

A scholar who has studied the Maya for 35 years said there is nothing ominous about 2012, despite the hype surrounding claims to the contrary.

"The trendy doomsday people... should be treated for what they are: under-informed opportunists and alarmists who will move onto other things in 2013," said John Major Jenkins, whose books include "Galactic Alignment" and who describes himself as a self-taught independent Maya scholar.

Jenkins said that cycle endings were all about transformation and renewal -- not catastrophe -- for the Maya. He also makes the case that the period they chose coincides with an alignment of the December solstice sun with the center of the Milky Way, as viewed from Earth.

"Two thousand years ago the Maya believed that the world would be going through a great transformation when this alignment happened," Jenkins said.

But Aveni said there is no evidence that the Maya cared about this concept of the Milky Way, adding that the galactic center was not defined until the 1950s.

"What you have here is a modern age influence [and] modern concepts trying to garb the ancient Maya in modern clothing, and it just doesn't wash for me," Aveni said.

Meanwhile, he and other scholars are bracing for growing interest as the date approaches.

"The whole year leading up to it is going to be just crazy, I'm sorry to say," Stuart said.

"I just think it's sad, it really just frustrates me. People are really misunderstanding this really cool culture by focusing on this 2012 thing. It means more about us than it does about the Maya."
