I have a Daughter who was born on Pi day. When she was little. she would tell you it's the second most important day, right after Christmas. Pi Day actually became a school wide fun day because of her, (small rural schools can be fun that way). We would bring a couple of pies for her math class to celebrate. Oddly, she much prefers a strawberry cheese cake for her birthday over pies.
I suspect she will NOT allow the change...........
