National Pi Day, March 14, is here! What is Pi Day and why is it so? It’s simple really—it’s because the date is 3/14, a.k.a the first three digits of the irrational number π (Pi). It’s a very punny day, if you can’t tell.

For those of us who aren’t mathematically minded, Pi Day is an excuse to eat and obsess over “pies,” both of the sweet and savory varieties. There are many restaurants that even offer deals on pie slices. If you’d like to partake in the tasty, geeky, and punny festivities, read on. Here’s everything to know about National Pi Day 2024, including ways to celebrate it.

What is Pi Day?

National Pi Day is a day created to celebrate the number π or “Pi” (3.1459…). Pi is the ratio of a circle’s circumference to its diameter. Since “pie” and “Pi” are pronounced the same way, Pi Day is used as an excuse to eat pies of all varieties, including pizza.

When is Pi Day 2024?

Pi Day is observed annually on March 14 because 3, 1, and 4 are the first three digits of Pi.

3. A pizza cutter

There's nothing like removing the perfect pizza (“pie”) out of the oven only to butcher the whole thing by cutting it unevenly with a knife, watching in horror as the cheese and toppings slip and slide over the sauce-slicked dough. To prevent such a tragedy from befalling your pizza, we recommend using our favorite pizza cutter, the Progressive PL8 Artisan Pizza Wheel. We love this pizza cutter thanks to its efficient cutting, comfortable handle and blade guard for safety.

6. A slow cooker

Pizza in a slow cooker? It may sound odd, but don't knock it until you try it. We did and we loved the result, so if you're looking for a convenient and fun way to make a thick, deep-dish pizza, you should give it a try. If you're in need of a slow cooker or simply want an upgrade, we've got just the one for you: the Cuisinart 6-Quart 3-in-1 Cook Central Multicooker. This is our favorite slow cooker because it keeps food at its optimal temperature whether you need to keep a dish warm or piping hot. Additionally, it’s dishwasher safe and its handles make it safe to carry it even when hot.
