International Day Of Mathematics

It’s probably no surprise to anyone with even a basic knowledge of mathematics that the International Day of Mathematics is observed on March 14th. After all, the date 3/14 corresponds to the numerical value of the mathematical constant pi (3.14). This holiday is organized and led by the International Mathematical Union and is supported by numerous other mathematical regional and international organizations.

The holiday has been observed since 2019 and is a day that spreads the word about the importance of mathematics around the world. Mathematics is something that can improve people’s quality of life and help solve current and future problems.

The History of the International Day of Mathematics

During the 205th session of UNESCO’s Executive Board, the International Day of Mathematics was first proposed. It was then adopted by UNESCO’s General Conference in November 2019.

The following year, this holiday was celebrated for the first time on March 14th. Its initial theme was “Mathematics is Everywhere,” and every year since then, a new theme has been chosen for the holiday’s celebrations to focus on a particular aspect of mathematics.
