Well, just as we’ve gotten our strength back from the revelries of Square Root Day (3/3/09) and Pi Day (3/14), its time to celebrate the next fabulous numerical holiday: Odd Day. Now, lots of dates are made up of odd numbers, but it can’t be an Odd Day unless the date consists of consecutive odds. That means, of course, that the next one won’t come along until July 9, 2011. So get out and celebrate in some odd way!!
