the mayan calendar didn't include leap years. it should have ended about 7 months ago. They also found another part to the calendar that goes on for like 2000 years. so nope I don't think it's going to end
I prank called a store asking if they got any deals or free deals on the end of the world day and they said no and hung up so... :D I don't think it's going to end until we die and when we do we wouldn't have to care anymore!
