**International Day of Mathematics 2023**: Every year on March 14, the International Day of Mathematics, also known as Pi Day, is observed to honour the mathematical constant Pi, which expresses the circumference to diameter ratio of a circle. The value for Pi is 3.14. Every year, all nations are welcome to take part in events that are open to the public and students in schools, museums, libraries, and other locations. The Executive Council of UNESCO declared March 14 to be the International Day of Mathematics at its 205th meeting.

**International Day of Mathematics 2023: Significance**

The purpose of the holiday is to recognise and celebrate the value of mathematics in our daily lives. Pi is a fundamental constant that is important for calculations, and scientists have studied and employed mathematics. Also, Albert Einstein’s birthday anniversary falls on this day.

**International Day of Mathematics 2023: History**

- In 1988, American physicist Larry Shaw recognised the day by planning a major party at the San Francisco Exploratorium. The initial celebration was carving a pie into the shape of pi and reciting the number pi to all possible decimal places.
- Syracuse mathematician Archimedes is credited with discovering Pi’s value for the first time. The scientific community eventually accepted the sign of Pi when Leonhard Euler used it in 1737.
- Pi Day will be recognised as International Mathematics Day in 2019 by the United Nations Educational, Scientific and Cultural Organization (UNESCO) at its 40th General Conference.
