THIS IS NOT THE MAYAN CALENDAR

By Mayan Avitable

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.  

KEPLER DISCOVERS PLANETARY SYSTEM ORBITING TWO SUNS

Lead author SDSU astronomy professor Jerry Orosz said it's the first transiting circumbinary multi-planet system to be found.

September 6, 2012 (San Diego) -- Astronomers at the International Astronomical Union meeting announced the discovery of the first transiting circumbinary multi-planet system: two planets orbiting around a pair of stars. This discovery shows that planetary systems can form and survive even in the chaotic environment around a binary star. And such planets can exist in the habitable zone of their stars.
