It’s officially March 14, which means only one thing: mmhmm pie.
March 14 is National Pie Day, a reference to the pi, a mathematical constant that is defined as the ratio of a circle’s circumference to its diameter. It appears all over mathematics and is approximately equal to 3.14.
To celebrate the number, and pie, restaurants and chains across the country offer deals for pie.
We’ve rounded up a few of them and shared them below.
