Where to find pizza and pie deals at Arizona restaurants

It’s not irrational to find pizza pies for $3.14 this Sunday.

March 14 is Pi Day, the annual celebration of the mathematical constant π (pi), which is the ratio of a circle’s circumference to its diameter. The trillion-digit ratio is rounded to 3.14.

Albert Einstein was born on Pi Day and noted astrophysicist Stephen Hawking died on the made-up holiday in 2018.

But you don’t have to be a math scholar to be acutely aware that Pi Day equals deals on circular food, including pies and pastries. Last year’s food holiday was slightly curtailed by the coronavirus pandemic, which happened as parts of the country were locking down.

However, unlike other big food deal days, Pi Day 2021 isn’t canceled though some of the deals have changed from past years with a few lasting longer than a day.
