- Every year on July 22, Pi Approximation Day is observed around the globe.
- It is dedicated to the Mathematical Constant Pi.
- This day is celebrated on 22 July because the approximation value of pi (22/7) is equal to 22/7 date.
- Mathematician Leonhard Euler designed the symbol of Pi in 1706.
- Pi Day is also observed every year on 14 March (3.14).
Pi
- This is a mathematical constant. It is represented by a Greek letter π.
- In 1706, pi use was introduced by William Jones.
