The Mayan calendar ends in 2012, which has led some people to wonder if perhaps the Mayans knew something that we don't. Since the Mayan civilization itself is long gone, and there is no record of the reason why their calendar was designed the way it was, this is all entirely speculative. There does not seem to be any good reason to think that a relatively primitive and long vanished culture could predict the end of the world more accurately than we can. More likely, they just thought that 2012 was so far in the future that there was no point in thinking about it.
No, we didn't (update of October 2013), and I know of no earth-shattering events that occurred on that date. Many uneducated people were led to believe that the Mayan calendar ended on December 12, 2012, but in truth it did not. It indicates a scheduled celebration sometime in the 4,000s, for example.
