    Purpose of use
    Understanding the Mayan concept of time and comparing the Mayan calendar to other ancient calendars.
    One minor typo: "1 long count=3 baktun" (above) should read "1 long count=13 baktun". Change the "3" to a "13". Also note that there was no year zero. According to some researchers the First Long Count date was actually (~ Aug 11, 3113 BC) and the Last Long Count date is actually, December 16, 2013. The day the Mayans dreaded has arrived. We're about to discover the meaning of the Dresden Codex. A giant crocodile spewing out green fire can't be a good thing. Hopefully it's just symbolic.
