# International Day of Mathematics on March 14th

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.

On November 26, 2019, the 40th session of the General Conference, UNESCO proclaimed March 14 as the International Day of Mathematics. The first official celebration will be on March 14, 2020.

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.

Please, go to the page of the event to discover all the events which will take place in your region.

Will you organize an event in your city to celebrate the International Day of Mathematics 2020? Tell us more!

We are preparing an interactive map of celebrations of the International Day of Mathematics around March 14 2020 for our official website (https://www.idm314.org/).

Will you organize a celebration, large or small, in a park, museum, school, library or any other public venue? Tell us more about your plans and we will include your city or country in the first version of the map.
