If you’re like me, you don’t need an excuse to eat pie. But a day like Pi Day, Monday, March 14, is a welcomed addition to the other 365 days this year, as eating pie in all its circular forms on this day is not just encouraged, but it’s celebrated.

In mathematics, Pi is the ratio of the circumference of a circle to its diameter, which is approximately 3.14159, although Pi extends over one trillion digits beyond its decimal point. It’s the 3.14 though that has led us to what is known as Pi Day during the calendar year—March 14 (3/14), appropriately. (I promise that I’m getting to the pie part where we dive in with our forks, so stay with me.)

“Pi is a constant number, meaning that for all circles of any size, Pi will be the same,” according to So if you look at a circular pie, like a Grandma Tobias Cherry Pie, the length around the edge of the pie when divided by its diameter (the width of the pie) will equate to Pi. The beauty of this number can even be linked to the Great Pyramid, as the perimeter of the pyramid when divided by its height is connected to Pi. When you combine all of that with the viral nature of the internet, you have the recipe for a cultural phenomenon. So whether you are looking to get in on the Pi Day fun or are excited by an excuse to eat pie, we invite you to come get your pie fix at DLM!
