Pi Day 2023 deals: For the love of math, snag a discounted slice of pizza at these restaurants

Tuesday equals deals on pizza pies.

March 14 marks Pi Day, the annual holiday in honor of the mathematical constant π (pi), the ratio of a circle’s circumference to its diameter.

The irrational number is typically rounded down to 3.14 hence why the celebration takes place on March 14, which has a numerical date of 3/14. The date also happens to be famed physicist Albert Einstein’s birthday and marks the anniversary of Stephen Hawking’s death.

While the day is really about math, many restaurants offer deals and discounts on circular food, including pizza and traditional dessert pies, to celebrate the holiday.

National Pi Day 2023: Here’s everything you need to celebrate

Why is Pi Day celebrated on March 14?

In 1988, Larry Shaw, a former staff physicist at the Exploratorium museum in San Francisco, linked March 14 (3/14) with the digits of pi (3.14) and celebrated the first Pi Day with fruit pies and tea. Shaw led Pi Day parades yearly at the museum until his death in 2017, according to the Exploratorium.

Pi Day became an annual tradition at the Exploratorium, and the celebration became an official U.S. national holiday in 2009. The U.S. House of Representatives resolution that designated Pi Day aims to encourage “schools and educators to observe the day with appropriate activities that teach students about Pi and engage them about the study of mathematics.”
