International Day of Mathematics - March 14 2023International Day of Mathematics (IDM) is annually observed across the globe on 14th March to create awareness about the importance of mathematics in addressing the challenges in areas like Artificial Intelligence(AI), climate change, energy and sustainable development.

  • The day also aims to highlight the significance of mathematics in improving the quality of life in both the developed and developing worlds.

The theme of IDM 2023 is “Mathematics for Everyone”.

The worldwide celebration of IDM is led by the International Mathematical Union (IMU) with the support of several international and regional organizations.


i.Executive Council of the United Nations Educational, Scientific and Cultural Organization(UNESCO) at its 205th session proclaimed March 14th as the International Day of Mathematics.
