It's a holiday that is all about numbers, pie (as in the food), and lots of circles.

I found some (3.14) interesting facts about PI.

1. It is an infinite and irrational number. It goes on for ever and never repeats.

2. some of the first numbers are 3.14... PI day is celebrated on the 14Th day of the 3 Month.

3. PI day is also Einstein's birthday

.14... i prefer pi is a palindrome.
