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.

The proclamation of March 14 as the International Day of Mathematics has been adopted by the Executive Council of UNESCO at its 205th session. It was adopted by the 40th session of the General Conference of the UNESCO in November 2019. The inaugural celebration of the IDM is on March 14, 2020.

From September 2019 it will feature:

  • Open source materials, projects, ideas and software
  • A map of worldwide events and gatherings
  • All content will be offered in multiple languages

A new theme every year: 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 theme for 2020 is:

Mathematics is everywhere

  • Mathematics help plan and manage economic and social systems enabling the move towards a sustainable use of resources.
  • We travel the world guided by precise mathematical calculations based on the position of the sun, stars and GPS satellites.
  • We explore the inside of the human body through CT scans and MRI by building images out of numerical data through mathematical algorithms.
  • We discover how human thought works by building AI software that can learn and make decisions through mathematic models.
  • We photographed a black hole and continue exploring the edges of the universe with mathematics.

The IDM is administered by the IDM Governing Board (IDMGB):
