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.

A new theme every year
Every year we'll 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 was proposed by Marco Zarco Rotairo of the Trece Martires City National High School at Indang, Cavite, Philippines.
The same theme had also been proposed for IDM 2022 by the London Mathematical Society, based on the priority to improve equality, diversity, and inclusion (EDI) in the mathematical community.
Others also proposed this theme, with slight variations in the wording. Blanca Margarita Parra Mosqueda, from ENES León, UNAM, León, Mexico, says:
