It’s not irrational to find deals including pizza for $3.14 this Monday.
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.
Pi Day, not to be confused with National Pie Day held in January or National Pizza Day in February, is usually a smorgasbord of deals on pizza, pastries and pot pies.
