    UNESCO proclaimed March 14 as the International Day of Mathematics on the 40th session of the General Conference on November 26, 2019.

Take a look back at the celebrations, themes and worldwide challenges of the
2020, 2021, 2022, 2023, and 2024 editions of the International Day of Mathematics.

THE THEME FOR 2026: MATHEMATICS AND HOPE

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.

Thales said, “Hope is the most universal of all human possessions.” More than 2,500 years later, we can also say that mathematics is one of the most universal human possessions.

Connecting hope and mathematics creates opportunities for deeper insight and knowledge. Mathematics gives us hope to understand reality and truth clearly, share common definitions, learn cooperation, use data responsibly, find win-win strategies, and more.
