## Why Celebrate Pi Day?

**Pi Day is celebrated on March** 14th (3/14 in the American date format) because the first three digits of pi are 3.14. Pi Day is a celebration of the mathematical constant pi, which is **the ratio of a circle's circumference to its diameter**.

Pi Day was first celebrated by **physicist Larry Shaw** in 1988 at the Exploratorium in San Francisco. Shaw, who worked at the museum, organized a celebration on March 14th at 1:59 PM (which corresponds to the first six digits of pi, 3.14159), which included marching around a circular space while eating fruit pies.

Since then, Pi Day has become a popular event in the mathematics and science communities, and is celebrated in many schools, museums, and other institutions around the world.** The purpose of Pi Day is to promote an appreciation of math and science, and to raise awareness of the important role that pi and other mathematical constants play in our lives**. Pi Day is a fun and educational way to celebrate the beauty and complexity of mathematics.
