Geometry nerds, rejoice: Pi Day 2020 is approaching! March 14—3/14—celebrates the mathematical wonder that is π, the first digits of which are 3, 1, and 4. In 2009, the United States began to recognize March 14 as Pi Day in celebration of the mathematical constant. Pi Day 2015 had extra special significance: On 3/14/15 at 9:26:53, the date and time together represented the first 10 digits of π.

Pi Day is also famous for its deals and freebies, often (but not exclusively) on pizzas and pies! Check out the best Pi Day deals for 2020.
