transposing the numbers buys us another week

You know that Mayan calendar thing, that supposedly predicts that the world will end this month?  Well, a lot of people were confused about which day of this month it's going to happen, thinking it was supposed to be 12/12/12 -- in other words, yesterday.  Even Jon Stewart on The Daily Show last night got it wrong.  No, no, no... The prediction is for the 21st of this month.... We've got a whole 'nother week before the end-of-the-world parties happen... followed by what?  --  the 22nd, maybe?
