Many people (apparently as much as 22% of Americans, even) apparently believe that the world is going to end, and that the Maya calendar has something to do with it all. Uhhh... No. It doesn't. Here are two good videos and a decent radio spot (with a conversation with a real, living, breathing Mayan).
Recently from SciShow:
Almost a year ago from CPG Grey:
Recently, on The Story Christina Croc sat down with Phoebe Judge to talk about growing up with the Mayan calendar and what it definitely does not say is going to happen on December 21, 2012.
If none of these - or other pieces of evidence - persuade you, then all I can say is to please just wait until December 22nd before you do anything rash. After all, if the end of the world is coming, you can't do anything to change it, but if it's a hoax, then you would have done something silly despite all the real evidence.
