December 12, 2012 is the date the Mayan calendar runs out and does not have anything to do with the end of time. I heard one of the rulers say that their calendar was never meant to predict the end of the world. It only meant that they wouldn't have a calendar after that date, but were working on a new or extended system and would take up where the old calendar ended.

Some people say that Nostradamus predicted that date as being the end of the world. It has no credibility because he was not a true prophet and more of his predictions have failed than have come true.

If you believe the Bible here is the one thing you can be sure of. When Jesus was talking to the disciples about the end of time (the coming of The Son of Man), he said, "But of that day and hour knows no man, no, not the Angels of Heaven, but My Father only." Matthew 24:36.
