Today, in myths!

Today, in math!

The challenge: take all three parts of today's date (day, month, and year, 2 or 4 digit) and subject them to some [U][B]simple[/B][/U] 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.

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 [url=http://www.imdb.com/title/tt0121127/]titillating[/url] 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.

Today is my birthday. I was born in 19xx. My age is: xx div 2

Happy b'day!
Today is a prime... if you write it viceversa (21028211)...

And the digit sum is prime as well.

[QUOTE=Uncwilly;319785]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.[/QUOTE]For today 12 - (12 - 2) = 2 the only even prime.

Today 31/12/2012 is the last day to not have unique digits in the year (since 31/12/1987).
