" celebrated each year on 14 March. Reason is that March 14 looks like 3/14 --> 3.14 when expressed in numerals. I like the holiday. My high school physics
teacher encouraged everyone to celebrate it. Some students in Universities
and high schools alike take the time to get some chalk and write out PI
to as many decmials as they can in one day, all over sidewalks
Quite the geek holiday.
