National Mathematics Day 2025

The observance was formally instituted by the Government of India in December 2011, and December 22 was designated as National Mathematics Day in recognition of Ramanujan’s extraordinary contributions to the discipline.

National Mathematics Day is observed every year on December 22 to commemorate the birth anniversary of Srinivasa Ramanujan, one of India’s most influential and globally recognised mathematicians. The day will be marked across educational institutions, research bodies and academic forums to highlight the importance of mathematics in scientific progress and everyday life.

December 22 marks the birth of Srinivasa Ramanujan, whose work continues to influence modern mathematics more than a century later. National Mathematics Day is celebrated to recognise his original thinking, his solutions to problems that were considered intractable during his lifetime, and the global impact of his discoveries.
