First of all, the Mayans don’t have a calender they have calendars which often interlocked. The calender that has given rise to the myth of the end of the world is the Mayan long count calendar. According to Mayan Mythology, we are living in the fourth world or “creation” so to speak. The last creation ended on 188.8.131.52.19 of the long count calendar. That sequence will occur again on December 20, 2012. According to the Mayans this is a time of great celebration for having reached the end of a creation cycle. It does not mean the end of the world but the beginning of a new “age”. Does the world end every December 31st? No – we go on to a new year. This is the same as the Mayan creation periods. In fact, the Mayans make many references to dates that fall beyond 2012.
