International Day of Mathematics 2026
March 14, 2026 in the World
The International Day of Mathematics is observed on March 14, 2026. It was proclaimed by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 2019 and has been marked annually since 2020. The date was chosen because it corresponds to the mathematical constant Pi (3.14), commonly celebrated as Pi Day.
The purpose of the day is to highlight the importance of mathematics in addressing challenges in science, technology, engineering and sustainable development. It promotes mathematics education and its role in innovation and problem-solving.
The International Day of Mathematics encourages educational institutions and communities to organize activities that make mathematics accessible and engaging. UNESCO supports inclusive participation to foster mathematical literacy and interest around the world.
