Happy Pi Day 2026! Today, Saturday, March 14, restaurants nationwide are rolling out the best Pi Day deals of the year — from $3.14 pizza pies to outright freebies. Whether you are searching for pie day deals near me or hunting the top pi day pizza deals 2026, this is your full guide to celebrating the pi number in the tastiest way possible.

What Is Pi and Why Is Pi Day on March 14?

Pi, or π, is the ratio of the circumference of a circle to its diameter. It is often shortened to 3.14, which is why March 14 — written as 3/14 — became the official day to celebrate all things pi.

Pi is considered a mathematical constant and is also infinite, meaning it is irrational. Long before computers, historic scientists such as Isaac Newton spent many hours calculating decimal places by hand. Today, using sophisticated computers, researchers have come up with trillions of digits for pi, but there is no end.

Pi Day itself dates to 1988, when physicist Larry Shaw began celebrations at the Exploratorium science museum in San Francisco. In 2009, Congress designated every March 14 as the official day — in the hopes of spurring more interest in math and science. Fittingly, the day is also Albert Einstein's birthday.
