Tweets to Prove my little "End of the World" Theory

I've been wondering something for the past days if the Mayan's Calendar ends on December 21st and ours ends on 31st (Because of New Years Eve) They can say "Oh it's the end of the world for them!" WELL THEY'RE WRONG IN MY OWN THEORY here's Why

I have a crazy theory why the Mayans "Thinks" the world will end - If their calendar ends on December 21st that means no Doomsday

Just their calendar ending on that day because we have thirty one days on December to go by and theirs only reach up to twenty one days.

So if that's the case then let's see what happens on December 21st 2012 and see if they're right or wrong!
