Pi Day Deals for Pizza AND Pie Lovers

Internationally, Pi Day is celebrated on March 14 annually. The special day is based on the mathematical constant pi, which is often represented by 3.14. Since the numbers of pi also correlate to March 14 (3/14), mathematicians like to use Pi Day as a celebration of numbers and mathematics. Ironically, even the famous mathematician Albert Einstein was born on March 14. However, since the word pi is also pronounced just like "pie," the day has also come to represent everyone's love of the classic American dessert.
