Actually, it is March 31st which is my mothers birthday. (yeah.. awww... ain't that sweet...etc..) Silly as it may sound, the older I get, the more I appreciate what that 84yo lady has done.

Pi day gets my vote because Pi is such a consistent thing. No matter what day it falls on or what it is applied to, it remains constant, and while that is certainly not unique, it is so easily remembered (non-math guy here, yes... I recall trig and pythagorean, but not much else) and fairly easy to spell too.... :-)

Additionally, it reminds me of the two Raspberry Pi's I play around with which are fantastic little Linux machines. And then there is the actual raspberry pie which my grandmother made, which is just a tiny bit harder to spell, but tasted very good.

And thus, Pi and Mom win out the day for this old farm boy.....
