Doom mongers and scientists who have been telling us about the Mayan calendar and the upcoming apocalypse in 2012 may have to cool their heels a while longer.  According to a new book titled "Calendars and Years II: Astronomy and Time In the Ancient and Medieval World", scientists used a Latin formula to convert the Mayan calendar, and that formula lost something in the translation.  The book's author reveals that the Latin and Mayan calendars are a bit out of sync, which means that our calculation for the end of the Mayan calendar may be off by as much as 50 to 100 years, but then again it may mean that the Mayan calendar has already ended and the world as we know it could be destroyed any day now.  Great, now I have to reschedule everything.
