Pi Day 2027 is Sunday, March 14.
Pi Day is named for 3.14, the first digits of pi. Pizza and pie places often sell a pizza or a slice of pie for $3.14 that day, almost always as a code in their app.
Deals for the day usually go live a few days before, often only in the restaurant's app or rewards program, and many end at closing that day. They show up on this page as soon as we find them.
