American Pie Council encourages Americans to celebrate Pi Day on March 14
Pi is a constant. So is pie. Throughout our lives it's always been there, like family and friends. The American Pie Council encourages people everywhere to make the time you spend together on National Pi Day just a little sweeter. Every year, National Pi Day circles around on March 14.
Pi, used to calculate the circumference of a circle, is over 4,000 years old. It is commonly rounded up to 3.14, marking March 14 as the official date to celebrate all things pi. With no repetition or pattern, pi is the only transcendental number that will continue infinitely - much like America's love for pie! To commemorate this delicious day, the American Pie Council encourages friends and families to get together and bake their favorite pie, share a pie with those in the community, host a pie party or even have a pie-throwing contest.
