Because Thanksgiving is not the only pie-centric holiday, we’re listing off some of Philly’s tastiest, flakiest treats.

Friday is March 14, a day that is mysteriously about math, pizza and pie. If you are looking to celebrate, here are some places to find deals on pizzas and pies in the Twin Cities to feast on, while you try to remember what comes after 3.

Pie day is March 14 or 3/14, which are also the same three digits in the mathematical constant Pi or 3.14159265359, or the number you need to memorize to calculate the circumference of a circle.

This year, though, it comes with some twists that won’t be seen again for a century. Pi Day, celebrated on March 14 (3/14), honors the number π (approximately 3.14), which represents the ratio of a circle’s circumference to its diameter.

Years ago, the infinite decimal 3.14 or its Greek symbol pi was mostly known to math and science geeks, but now March 14 is also a day for tasty deals.
