It is a breakthrough for mathematics to have its own International Day (IDM) every year on March 14, proclaimed by UNESCO. It follows an open, participative approach to connect all through a central portal, an interactive event map, activities, calls, videos, etc.

The first IDM “Mathematics is Everywhere” was held in 2020, with 1043 announced events in 110 countries. More than 18000 unique visitors joined the Global Live Launch event.

The IDM project is led by the IMU, website by IMAGINARY.
