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.
Join the 2024 celebration
The best way to celebrate the IDM is to host your own event.

The theme for 2024: Playing with Math
Every year we announce a theme to flavor the celebration, spark creativity and bring light to connections between mathematics and all sorts of fields, concepts and ideas.
In 2024 we want to celebrate mathematical games, puzzles and other entertaining activities, but also "playing" with mathematics itself, exploring, experimenting, and discovering.
Play with the theme!
In some languages the verb play means other things, like "performing" and instrument, or "acting" in a theater.
What other ideas does the theme bring to people's minds in your language? You should consider them when planning activities for your celebration.
These are the official translations of the theme to different languages:
