**What is Pi Day and why do we celebrate it? **

Pi Day is a celebration of the mathematical constant π (pi). Pi has been calculated to be approximately 3.14159, and March 14th (3/14) is therefore celebrated as Pi Day each year. The date was chosen because 3, 1, and 4 are the first three digits of π.

One common way to celebrate Pi Day is by eating pie. There are many different types of pie, but most people seem to prefer apple or cherry pie on Pi Day. Pi can also be celebrated by doing math problems or discussing the history of π.

Some people believe that Pi Day should be a more important holiday than it is currently. They argue that pi is one of the most important constants in mathematics, and that more people should learn about it and celebrate it.

**What are three things people do to celebrate Pi Day?**

Pi Day is celebrated on March 14th (3/14) annually. Pi is the ratio of a circle’s circumference to its diameter and is approximately 3.14159. Pi has been calculated to over one trillion digits beyond its decimal point, and people have been fascinated by the number for centuries.

There are a few different ways that people celebrate Pi Day. Some people recite as many digits of pi as they can, others eat pie, and some even participate in Pi Day races. A Pi Day race is where runners try to complete a mile-long race in the shortest amount of time possible. The record for the fastest mile is 4 minutes and 33 seconds, set by James Hird in 2014.

Whether you recite pi digits, eat pie, or run in a race, be sure to celebrate Pi Day this year!

**Why is March 14th Pi Day?**

Pi Day is celebrated on March 14th because it is the 3.14 date which corresponds to the mathematical value of Pi. Pi is the ratio of a circle’s circumference to its diameter and has been calculated to over one trillion digits beyond its decimal point. The irrational number has been used in geometry, engineering and physics throughout history and continues to be an important part of mathematics today.

Despite its importance, Pi remains a mystery and there is still no agreed upon proof as to why it exists. Some mathematicians believe that Pi is simply the result of using a certain type of infinite series in calculus while others think that it could be related to the geometry of shapes in higher dimensions. Regardless of the reason, Pi continues to amaze researchers and mathematicians with its unique properties and seemingly endless possibilities.
