The 2023 International Day of Mathematics
This was the fourth celebration of the IDM since UNESCO proclaimed it in 2019.

The theme was proposed by Marco Zarco Rotairo of the Trece Martires City National High School at Trece Martires City, Cavite, Philippines.
The same theme had also been proposed for IDM 2022 by the London Mathematical Society, based on the importance of improving 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, Mexico, says:

The Mathematics for Everyone Comic Challenge
To celebrate the 2023 IDM we invited you to participate in our Comic Challenge by sending us a comic with mathematics created by you.
Like every year, people from all over the world showed their creativity, artistic skills, and ability to bring mathematics to everyone. We put some of the best submissions in a gallery of featured comics, and we also made an interactive map to explore and discover comics from all over the world.
In 2023, people and organizations all over the world announced events in their cities:
