But you don’t have to enjoy math to celebrate the offbeat holiday. Many people celebrate by going all out with pizza pies, fruit pies, pot pies or any other round food they can conjure up.
Pizza chains and bakeries across the country often offer specials, selling treats to customers for $3.14. In Springfield, Bada Bing! Pizzeria, located at 40 N. Fountain Ave., will give away free 10-inch cheese and pepperoni pizzas until 9 p.m. in exchange for a charitable donation.
Kroger also has a sale on peach or cherry pies for the special price.
A lot of major pizza chains, including Domino’s, Pizza Hut and Papa John’s, also will have special discounts running so you can still celebrate with your own piece of the pie.
