The challenge: take all three parts of today's date (day, month, and year, 2 or 4 digit) and subject them to some simple math to get an interesting result or make some interesting observation about a standard representation of the date. Is intended to be a one post a day thread. The first person to post on a date (during that date in their locale) is it, no one-ups-manship. A couple of examples: A few days ago it was November 21st, 2012. Written YYMMDD it was 121121, a palindrome. Today was/is November 27th, 2012. YY+MM+DD is 12+11+27=50 that is a nice round number.
 2012-11-28, 02:26 #2 ewmayer ∂2ω=0     Sep 2002 Repรบblica de California 13·29·31 Posts For today's date, if I form MMDDYYYY into a valid 7-digit IMDB movie index by retaining the last 3 digits of the year, I get 1127012, which yields a rather titillating title. Anyone have a copy of this classic in their collection? Trying the same experiment with YYYMMDD format yields what appears to be a Bollywood song-and-dance thang, cannot tell if it was a hit or a 'bust' at the box office.

And the digit sum is prime as well.

For today 12 - (12 - 2) = 2 the only even prime.
