4 Days 'Til Doomsday? Not Really

The end is near, according to some — but experts say not to put stock in the Mayan Apocalypse rumors that claim the world will end on Friday.

The date, Dec. 21, 2012, corresponds with the end of the 13th b'ak'tun of the ancient Maya Long Count Calendar. This calendar is one of several developed by the Central American empire that collapsed around A.D. 900. The 400-year-long b'ak'tun is only one of the units of time the Maya used to mark cycles in their calendar, according to University of Texas Maya hieroglyph expert David Stuart. The complex, cyclical calendar included at least 24 different units of time both shorter and longer than b'ak'tuns, Stuart said.
