It's a day that brings math lovers, sweet-toothed pie enthusiasts and pizza fanatics together — National Pi Day.

National Pi Day 2018 — which celebrates the mathematical constant shortened to 3.14 and is naturally held every year on March 14 (3/14) — includes a long list of deals on pizza (pie) and regular pie-pie.

The March 14 holiday often feature prices discounted to (yep) $3.14, and sometimes, you can simply get free pie.

While there are no National Pi Day deals per se this year from Domino's or Pizza Hut, each pizza chain has its own ongoing deals, like buy-one-get-one-free at Domino's now through March 18, and $5.99 two-topping medium pizzas at Pizza Hut when you buy at least two.

Here are all the best 2018 National Pi Day deals at participating locations, including special offers from Whole Foods, Boston Market, and Blaze Pizza.
