Celebrated around the world on March 14, the excitement of hungry bargain hunters multiplies on National Pi Day because of all the deals and discounts.
What’s National Pi Day? The Greek letter Pi (symbol π) represents a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. As March 14 is also written 3.14, it’s the ideal day to celebrate pi and, more importantly, pie.
Bargain hunters and pie lovers can join mathematicians in the fun and frivolity of March 14, thanks to all of the National Pi Day deals offered by national and local restaurants.
