Pi Day is March 14, 2015. And this year's math celebration is more important because 3/14/15 at 9:26:53 the first 10 numbers of pi will be chronological. If you're in North America, this will happen twice at AM and PM. This date is important for Pi Day because it only happens once every one hundred years.
