Apparently, the Mayans said the world would end today, which is not true. What was really written down in hieroglyphics, was that the 13th bak'tun would end. A bak'tun is a period of time, about 395 years. The calendar then made a reference to the ceremony that would happen every time a bak'tun ended. Just because it said that the bak'tun was ending, it does not mean they did not expect the 14th bak'tun to start. The knot reason people started spreading it was the end of the world, was to make a profit. It's all a hoax, the world was never going to end.
