Why We Celebrate Pi Day with Pizza and Pie

The connection between the mathematical constant $\pi$ (Pi) and circular food items like pizza and dessert pies is a cultural phenomenon that has only grown since the holiday's official recognition. Pi Day is held annually on March 14th because the date (3/14) represents the first three significant digits of the irrational number.

The holiday was formally founded in 1988 by physicist Larry Shaw at the San Francisco Exploratorium. Shaw, often referred to as "The Prince of Pi," organized the first celebration which involved staff and the public marching in a circle and then consuming fruit pies. Over the decades, the tradition has expanded, with pizza—a savory, circular "pie"—becoming an equally popular centerpiece for the festivities.

Interestingly, March 14th is also the birthday of one of history’s most famous scientists, Albert Einstein, adding another layer of intellectual celebration to the day. For foodies, however, the reasoning is simple: the deals are too good to pass up, making it a perfect excuse to indulge in various pizza styles, from Chicago deep dish to classic Neapolitan.

Beyond Pizza: Pi Day Dessert Deals and Other Entities

While pizza is the star, the original intent of Pi Day was to celebrate with dessert pies. Many restaurants and chains offer discounts on circular desserts, rounding out your mathematical meal. These deals are great for maximizing the topical authority of your Pi Day feast.

• BJ's Restaurants & Brewhouse: $3.14 Pizookie. BJ's is famous for its Pizookie, a warm, fresh-baked cookie topped with ice cream. On Pi Day, you can often snag this delicious dessert for just $3.14, a perfect way to cap off a pizza dinner.
• Burger King: Though not a pizza chain, Burger King has previously participated in Pi Day by offering deals on their circular menu items, such as a free or discounted Hershey's Sundae Pie.
• Goldbelly: This online marketplace for gourmet food often features special Pi Day collections, offering discounts on famous dessert pies from bakeries across the country, allowing you to ship a classic fruit pie right to your door.
• Crust Pizza: Look for regional chains like Crust Pizza to offer their own unique Pi Day specials, often involving a percentage discount or a free side with a large pizza purchase.

To ensure you get the best deal, always check the fine print. Most offers require you to use a specific promo code, order through a mobile app, or be a member of the restaurant's loyalty program. The demand on March 14 is enormous, so placing your order early in the day is highly recommended to avoid long wait times and potential sell-outs. Enjoy your 2025 Pi Day celebration with as much delicious and discounted pizza as possible!
