You don’t have to love math to love Pi Day deals, but you’ll love how the numbers add up with discounts on pizza and pie.

Every year on March 14 we celebrate the math component that helps us find the circumference of a circle (π = 3.14 for short, although there are a lot more numbers after that). And although it started as a way to bring awareness to mathematics, it has deliciously morphed into the biggest pizza-themed food holiday of the year — beating even National Pizza Day for having the best and most deals.

Here are all the Pi Day deals and food discounts we expect to see on March 14, 2025, including Pi Day deals at Pizza Hut, UNO, Blaze Pizza and more.

Pi Day celebrates circles with one-day Pi Day deals on pizzas and pies.

national-pizza-day-papa-johns-kcl-model-14

Want to calculate the circumference of a pie (or a pizza pie)? You’ll need to include Pi in your calculations. Every year on Pi Day, March 14, restaurants roll out deals on circular items like pizzas, pies, and pot pies – plus a few non-round things like a rotisserie chicken meal.

Pi Day is happening next year on Friday, March 14.

The value of Pi never changes (3.14… etc.), and so neither does Pi Day. It’s a federally recognized holiday that is always on 3/14 — no matter what day of the week that is. Next year, it happens to fall on a Friday.

While all of the various Pi Day deals take place on March 14, some restaurants offer discounts a few extra days.
