You don’t have to be a math scholar to be acutely aware that Pi Day equals deals on circular food.
Saturday, March 14 marks 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.
Pi Day, not to be confused with Pie Day held in January, is usually a smorgasbord of deals on pizza, pastry and pot pies, but the coronavirus pandemic may affect some of these offers so call ahead.
Blaze Pizza announced Thursday that it has canceled its annual Pi Day event, which draws large crowds, because of the increased impact of COVID-19. It’s replacing the one-day $3.14 pizza offer with a “Pi Day reward” redeemable Monday through the end of the year. To get the offer, you have to download the app by Sunday.
