Pi isn’t just a term you see in math problems. It’s a special number with its own unique day.
Pi Day is celebrated every year on March 14 because the date aligns with the first three digits of pi – 3.14. In 2025, Pi Day falls on a Friday.
Pi shows the relationship between the circumference and the diameter of a circle and is critical in important mathematical calculations. Thus, most Pi Day celebrations revolve around delicious, circular pies.
Here are some fun activities to celebrate the day in the D.C. area.
