From a mailing-list "Today is November 19th, 1999. The numerical format for today is 19-11-1999. All of the digits are odd. The next Odd day will be 1-1-3111 - which is well over a thousand years away, which we will never see. Days such as 13-4-89 have both even and odd digits, thus, it is neither odd nor even. The next even day will be 2-2-2000 - the first one since 28-8-888. So, now you have a reason to celebrate this Friday as it'll be your last odd day on Earth!!!!!!" So Slashdot wishes you a nice odd day!
