International Day of Mathematics or Pi Day is celebrated on March 14 every year to recognise the mathematical constant, Pi, which defines the ratio of a circle's circumference to its diameter.
The value for Pi is 3.14.
The day is celebrated by various schools, universities, and mathematics organisations globally with a unique theme with an aim of promoting mathematics education and awareness.
The theme for Pi Day 2023 is "Mathematics for Everyone", proposed by Marco Zarco Rotairo from Philippines' Trece Martires City National High School, according to the official website of the celebration.
The day was recognised in 1988 by physicist Larry Shaw as he organised a large-scale celebration at the San Francisco Exploratorium in the United States.
It was first celebrated by cutting a Pi-shaped pie, and the recitation of the value of pi to as many decimal places as possible.
The value of Pi was first calculated by a mathematician named Archimedes of Syracuse. It was later accepted by the scientific community when Leonhard Euler used the symbol of Pi in 1737.
In 2019, the United Nations Educational, Scientific and Cultural Organisation (UNESCO) in its 40th General Conference decided to observe Pi Day as International Mathematics Day.
