Here's a random 'fact': Today, October 5th, is THE most common birthday in the U.S.
There's no definitive reason behind it...it's based on a survey from 2001 asking people about their birthday. And more people named October 5th as their birthday than any other date.
But, today IS nine months after New Year's Eve. And a lot of people have sex on New Year's Eve, right?
Supposedly May 22nd is the least-common birthday...other than February 29th, which doesn't really count, since it only happens once every four years.
