December 15, 2012 (San Diego's East County)--With all of the news surrounding the Mayan Apocalypse supposedly taking place on December 21, 2012, one aspect of the coverage has been glaringly incorrect. The graphic above has been used as an example of the Mayan Calendar. It is not. It is the Aztec Calendar. In fact, the Mayan Calendar is much more complicated.

The Mayans used a combination of three calendars: Haab, Tzolkin, and the Calendar Round. The Mayan calendar of 365 days is called Haab.  It is divided into 18 months of 20 days, each with a period of 5 days left over at the end of the year. This short 5 day month Uayeb was often seen as a dark time.
