I've got some news that might make you feel odd, quite literally (or maybe I should say, mathematically).
Today is 5/7/09, one of a few instances when three consecutive odd numbers make up the date. As a matter of fact, it's one of only six times this will happen in the century. Today is the third this century.
If you think Pi Day (March 14) is special, note that it happens 100 times in a century. So, mathematically, today is about 16.66 times more special than Pi Day.
