Announcing the International Day of Mathematics: March 14

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 25 2019, the 40th General Conference of UNESCO has proclaimed March 14 (Pi Day) as the International Day of Mathematics (IDM). The project of International Day of Mathematics is led by the International Mathematical Union. The official launch will be in 2020. 

Considering that March 14, 2020 is a Saturday, the launch at the UNESCO Headquarters in Paris will take place on Friday March 13, 2020. A simultaneous African launch will be held at the Next Einstein Forum in Nairobi, Kenya.

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 2020 theme is 

Mathematics is Everywhere

  • Mathematics is everywhere in science and technol­ogy.
  • Mathematics is everywhere in the organization of the civilization. 
  • Mathematics is essential to meet the UN Sustainable Development Goals.
  • Mathematics is everywhere in whatever you do.
  • Tell me about some activity or area and I will tell you where mathematics is.

Beginning  December 2019 on the web site you will be able to:

  • Find open source material related to the theme: pro­jects, ideas and software for use in classrooms, large events or in small activities for children and the general public.
  • Find instructions on how to organize an event.
  • Post your activities on an interactive map.
  • Explore the activities around the world.

How will you celebrate?

  • Will you celebrate in your classroom?
  • Do you wish to organize a small exhibition and/or interactive activities with your local community?
  • Will your national mathematical society or mathe­matics teacher association organize national ac­tivities?
  • Will you celebrate with a neighbouring country

Start thinking on how you will celebrate. We are here to help.
