I first learned about Pi Day when my daughter was in Middle School. I wondered where this day had been my whole life! Now a global tradition almost 30 years old, Pi Day is best celebrated at 1:59 p.m. on March 14 to match the first few digits of the number Pi (and the extent of most people’s memorization, 3.14159), with a pie, of course – savory or dessert version.
Math moment: What is Pi anyway? Ahem – Pi is the number expressing the ratio of a circle’s circumference to its diameter. It’s used in engineering, science and statistics and begins with 3.14 and goes on into infinity. It’s also captured a lot of people’s imaginations. The record for Longest Pi Recitation belongs to Japan’s Akira Hawaguchi, who recited from memory an astounding 100,000 digits over 16+ hours. How is that even possible?? (Here are some tips for memorizing pi.) A teen holds the North American record.
It seems Pi Day as we know it didn’t catch on until about 30 years ago, when it was begun at the San Francisco Exploratorium. Now it is celebrated around the world. Try some of these Pi Day games and activities from the Exploratorium, where Pi Day began!
I’ve gathered a few pies to help you celebrate. It seems like a more fun way to mark the day than memorizing digits. But, to each his or her own!

This is my own recipe for Classic Apple Pie. You could add a Pi symbol in crust (or cut out a Pi symbol) to the top of this, or any, pie.
When I think of Pie Mavens, I think of my friend Leah Brooks and her stunning and sometimes unexpected fruit pies, like apple with thyme or double lemon blueberry, or her chocolate cream, pumpkin, lattice-topped cherry, or perfect pecan pies!
Happy Pi Day!
