Mayan Apocalypse on my Day Off! Dang It!

Wouldn't you know that the first day I take off in the last two months falls right on the so-called "Mayan apocalypse" 12/21/12.  It better not cheat me out of a little rest and relaxation.  I was planning on getting my final x-mas shopping done.  It would be a real disaster if I don't have a gift for my mother-in-law.  Then the world probably will end on 12/25/12.
