Well apparently, all the experts have been trying to say - including descendants of the Mayans, is that all this actually meant, was it was the end of that current Mayan calendar - exactly the same as the western calendar now in use will end on 31st December, this and every single year.
It's nothing more than that - it isn't some end of the world thing, it's simply the end of a now long defunct calendar used by some people whose civilisation died out some hundreds of years ago.

Still, it's more dramatic to pretend it's the end of the world isn't it I could have guessed a lot of this is in America!
