Create a Perl script to pick a random month and day, hahaha :). Just kidding, just reading over the reasponses I have seen, I second kutsu's suggestion of Dec. 23, it seems logical :).

I was not lurking around the monastary, yet, so I have not picked up on many of the honored tradions, but maybe have people post obfu that prints something like "Happy PM day," we could call them JAPM :). It would all be dedicated to those saints who have made this great community what it is today.
