The International Day of Mathematics (IDM) is a worldwide celebration. Each year on March 14 all countries will be invited to participate through activities for both students and the general public in schools, museums, libraries and other spaces.
March 14 is already celebrated in many countries as Pi Day because that date is written as 3/14 in some countries and the mathematical constant Pi is approximately 3.14.
The International Day of Mathematics is a project led by the International Mathematical Union with the support of numerous international and regional organizations.

A new theme every year
Every year we'll 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 the 2022 International Day of Mathematics is Mathematics Unites
It was proposed by Yuliya Nesterova, a graduate student from the University of Ottawa in Canada. She explains:
“Mathematics unites, to signal that it is a common language we all have and a common subject with which to find one another.”
