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.

For those of you wondering “What is Pi Day?” — every year on March 14 (3.14 — get it?) we celebrate the math component that helps us find the circumference of a circle (π = 3.14159265359 … ).

But this food holiday is really an excuse to enjoy our favorite kinds of circles — pies and pizza pies — for cheap.

Pi Day is always on March 14.

Pi Day, not to be confused with the not-as-big-holiday National Pie Day on Jan. 23, occurs every year on March 14 (also Einstein’s birthday). In 2024, this food holiday falls on a Thursday. While we know Pi Day for its pizza deals, when launched in 1988 by physicist Larry Shaw, it was a day for celebrating the number and mathematics. In 2009, the US House of Representatives approved a resolution that recognized Pi Day, with the aim of inspiring schools, teachers, and students to participate in math-related activities.
