# Pi Approximation Day 2022 – Know Date, Meaning, History, Significance and How to celebrate this day?

Every year on July 22, Pi Approximation Day is observed to honour the mathematical constant pi (π), which is represented by the Greek letter pi and approximates to 3.14. This day is dedicated to honouring and celebrating the work done by numerous scientists and mathematicians in their pursuit of discovering the value of pi.

Pi is a mathematical constant that is represented by the symbol and is pronounced “pie.” It serves as a symbol for a mathematical constant and is the 16th letter in the Greek alphabet. The circumference to diameter ratio of a circle is approximately 3.14159. The number irrational is.

People who write their dates in the date/month format observe Pi Approximation Day on July 22 or 22/7 (π=22/7), which has very unique significance. Since the fraction’s simplified value is 3.14 on March 14, some people who write their dates in month/date format choose to observe Pi Approximation Day on that day.

### History of Pi Approximation Day:

In 1988, Larry Shaw, a worker at the Exploratorium science museum in San Francisco, California, launched Pi Day. At the San Francisco Exploratorium, Larry Shaw had planned a big Pi Day celebration, which frequently involves staff members and visitors marching around a circular area while enjoying fruit pies.

The United States House of Representatives officially recognised March 14 as National Pi Day on March 12, 2009, with the passage of resolution 111 H. Res. 224. Furthermore, Pi Day was declared the International Day of Mathematics in November 2019 by the 40th General Conference of UNESCO.

### Significance of Pi Approximation Day:

Pi Approximation Day was created to recognise and honour the work that many scientists and mathematicians have put into discovering the value of pi. It is vitally crucial to remember the approximate value of pi, hence Pi Approximation Day is very important.

Pi, according to mathematicians, has been around for approximately four thousand years. Additionally, it’s thought that in the 1700s, mathematicians started using the Greek letter. Welsh mathematician William Jones introduced the pi sign in 1706. Later,

The famous mathematician Leonhard Euler, who was born in Switzerland, popularised the symbol in 1737. Georges Buffon, a French mathematician from the 18th century, created a method for computing based on probability.

### How is the Day of Pi Approximation Celebrated?

There are several ways to celebrate Pi Approximation Day, including eating lots of pie and talking about the significance of the Pi. Additionally, on this day, a lot of institutions, schools, and education classes hold competitions to see which student can recall Pi to the most decimal places. Additionally, they organise a number of fun Pi games for the students.

A pie with a decoration on top can also be baked to honour Pi Day. You may play a game with your pals where the object was to memorise the highest value of Pi without repeating any patterns. Since it is a fundamental mathematical constant, mathematicians celebrate this day.
