International Day of Mathematics

International Day of Mathematics

International Day of Mathematics (IDM) is observed on March 14 every year. The day aims to celebrate and highlight the importance of maths in the world, especially the role it plays in breakthroughs in science and technology. The day is also known as Pi Day because the constant π (pi) is approximately rounded to 3.14 and the date is written as 3/14 in some countries. It’s a day for a double celebration!

Mathematics is a critical part of life and essential in our daily activities. You may not realize it, but you use math every single day! From cooking dinner to telling time, your brain is constantly busting equations. And just like every other aspect of our lives that we hold dear, we ought, and can celebrate the special day in this fantastic field.

A new theme every year: Every year we will announce a new theme to flavor the celebration, spark creativity and bring light to connections between mathematics and all sorts of fields, concepts, and ideas.

The theme for 2023 is: Mathematics for Everyone


United Nations Educational, Scientific and Cultural Organization (UNESCO) has declared 14 March, also known as Pi Day, as the International Day of Mathematics in its 40th General Conference on 25th November 2019 (40C/ Resolution 30). IMD celebrates the beauty and importance of mathematics and its essential role in everyone’s life.

UNESCO is committed daily to facilitating access to mathematics education and research in developing countries through its educational programs, but also through its regional centers dedicated to mathematics.

The day deciphers the role of mathematics in achieving the Sustainable Development Goals for 2030 that was adopted by the global community in 2015. The International Day of Mathematics project is led by the International Mathematical Union with the support of numerous international and regional organizations from all over the world. The International Mathematical Union (IMU), a nongovernment, non-profit scientific organization that promotes international cooperation in mathematics, leads the IDM. The IDM aims to contribute to the achievement of the Sustainable Development Goals (SDGs), specifically.
