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.
People and organizations all over the world are already preparing events in their cities:
