The Mayan Calender ends 12-21-2012, and that's kind of scary since it's not far away. Although, I read somewhere there was an error in calculating the date (because of calendars, the actually length of a year, etc), and it was October 28, 2011. Either way, we all know something's going to happen around that time. I read a book on it once, although it was science fiction, some of the information was true in it.
