For those keeping track today's date, 5/7/09, is one of only six this century that will feature three consecutive odd numbers. Numbers lovers say the rare occurrence is an excuse to celebrate.

"The previous stretch of six dates like this started with 1/3/1905 — 13 months after the Wright Brothers' flight," said Ron Gordon, the Redwood City teacher who enthusiastically promotes these numerical holidays, like Square Root Day on 3/3/09.

If you want to know more about it then go to Odd Day, there is even a prize of $579 to celebrate today's odd date.
