Pi Day Deals, Freebies, and Events for Math Lovers and Haters Alike


March 14, 2015: Pi, or π, is the ratio of the circumference of a circle to its diameter. It’s usually shortened to 3.14, which is why March 14 is celebrated every year as Pi Day, but it’s an irrational number that continues infinitely without a pattern, like so: 3.14159265358979323846264338327950288419716939937510582…

The year 2015 marks a very special Pi Day, one that comes only once a century: 3.14.15. Hence some once-in-a-lifetime Pi Day celebrations and promotions around the country are planned for this Saturday.

But what’s the big deal about pi in the first place?

“To mathematicians, pi is a powerful superhero that turns up all the time in a huge range of mathematical problems,” Keith Devlin, Stanford University mathematician and the NPR “Math Guy”, explained recently to USA Today. “Pi deserves its special day.”

Unsurprisingly, the are many Pi Day promotions that’ll get math nerds excited: For instance, the American Mathematical Society is discounting its publications (40% off for members, 25% off for nonmembers) for orders placed using the code MT159 from March 14 through the end of the month. It’s just like Black Friday!

There are plenty of deals meant to appeal to C students who hated math too. The fast-casual Blaze Pizza chain is offering any pizza for $3.14 on Pi Day. Your Pie, a pizza restaurant franchise in the southeastern U.S., is knocking $3.14 off pizzas and handing out free gelato and pi-related swag on Saturday. Up in New England,Portland Pie Company locations host an annual customer appreciation day on Pi Day, and on 3.14.15 they will be selling $3.14 pints of beer, $3.14 kids meals, and $3.14 10-inch specialty pizza pies.
