When is National Pi Day? This holiday is always celebrated on March 14

National Pi Day celebrates Pi, a mathematical concept and a number that never ends….at least no one  and no computer has found the end yet. Often, we round it off to 3.14. If you are a mathematician, this is your day. For National Pi Day is a celebration of mathematics. And, more specifically…. it celebrates “Pi”. 

So, what is Pi? Pi is a constant is used to calculate the circumference of a circle from the circle’s radius or diameter. It is an irrational number, meaning it can be calculated to an infinitesimal number of decimal places. Computers have been used to calculate and have not found the end decimal place, meaning there isn’t one.

Today is the birthday physicist Albert Einstein. Einstein was born on March 14, 1879. The date is also represented as 3.14. We strongly suspect some combination of these two facts is why someone created the day on March 14th. However, “Pi” was around long before Albert Einstein was born.
