Pi Day

March 14 is commonly referred to as Pi Day, a day that aims to celebrate the ratio of the circumference of a circle.

The number is known as 3.14 or π and can actually go on forever. The most accurate value for Pi, according to Guinness World Records, is more than 62 trillion digits (62,831,853,071,796 to be precise), calculated in August 2021 by the University of Applied Sciences in Switzerland.

While the day is popular in math circles, it is also a day for those looking to score great deals on actual pie, pizza pie and other circular treats.
