Every year on March 14, people all over the nation celebrate Pi Day.
Every year on March 14, people all over the nation celebrate Pi Day.
The day honors the mathematical concept of pi -- the ratio of a circle's circumference to its diameter that is approximately equal to 3.14159.
Because pi is an irrational number, its digits do not repeat, and the approximate number 3.14 is often used for everyday calculations, according to the Encyclopedia Britannica.
Physicist Larry Shaw founded Pi Day in 1988, however, it wasn’t until 2009 that the U.S. House of Representatives passed legislation to formally recognize the holiday.
From pizza pies to dessert pies, many businesses and restaurants are offering deals to celebrate.
