Will somebody please 'splain to me where they predicted "the world was coming to an end" ???
All I know is that their calendar ran out.
My calendar runs out every year, I don't get that excited about it.
OMG!!! Get one of those that has a couple extra months, for God's Sake!!! You're risking setting off the apocalypse, jerk!!!
But it ran out of numbers in 1999, killing approximately 99% of the human population leaving the rest to live on the flesh of the dead... or something like that.
If the Mayans predicted the end of the world AND they had a history of correct predictions without going through some Nostradamean back flips to make the facts make the prediction, then I might consider worrying. Otherwise I'll put it with the other doomsday predictions which have had a accuracy rate of 0.00000% out of the last few thousand attempts.
The Mayan calendar just indicated and end of one cycle and the beginning of the next.
