From USA Today:
March 14 is Pi Day, an 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.Celebrate Pi Day with Pi Day 2019 Deals
Albert Einstein was born on Pi Day and last year noted astrophysicist Stephen Hawking died on the made-up holiday.
Pi Day, not to be confused with Pie Day held in January, is a day with deals on pizza, pastry and pot pies.
Aside from calculating your savings, it's a day to have fun with math too, said Syracuse University mathematics professor Graham Leuschke. He said you can search for your birthday in the digits of π and can create a "pi-ku" similar to a haiku poem.
