National Mathematics Day (India)2026 · Date · History · Messages
The Government of India announced 22 December, Ramanujan’s birthday, as National Mathematics Day in 2011; a later Press Information Bureau release states that National Mathematics Day is celebrated each year on 22 December.
About National Mathematics Day (India)
National Mathematics Day in India is observed on 22 December, the birth anniversary of mathematician Srinivasa Ramanujan. The day is intended to increase awareness of mathematics and recognise Ramanujan’s influence on mathematical research.
The Government of India publicly announced the designation on 26 December 2011 during the 125th birth-anniversary celebrations of Ramanujan in Chennai. The same announcement designated 2012 as the National Mathematical Year.
Why National Mathematics Day (India) matters
The observance uses Ramanujan’s life and work as a starting point for wider engagement with mathematics—from school learning to advanced research. Official material presents the day as a way to encourage the study of mathematics and make more people aware of Ramanujan’s contribution.
Because mathematical work extends far beyond one person or one field, a strong observance can combine historical learning with problem solving, teaching, research and discussion of how mathematics is used across science and society.
History of National Mathematics Day (India)
Srinivasa Ramanujan was born on 22 December 1887. His work made lasting contributions to areas including number theory, infinite series and continued fractions.
On 26 December 2011, Prime Minister Manmohan Singh announced that the Government of India had decided to declare Ramanujan’s birthday, 22 December, as National Mathematics Day. The announcement also designated 2012 as the National Mathematical Year.
Later Ministry of Education and Government of India material continues to identify 22 December as National Mathematics Day. The reviewed sources do not establish a separate founding statute or a directly documented first celebration date, so those details remain open.

How to Observe National Mathematics Day (India)
Try a mathematics problem or puzzle that is challenging enough to require explanation, not just a final answer.
Read about one area of Ramanujan’s work and use a reliable source to understand what made it mathematically important.
Organise a classroom or community activity that shows how mathematics appears in computing, finance, engineering, statistics, design or everyday decision-making.
Use the day to discuss mathematics anxiety and teaching methods that make reasoning more accessible without reducing mathematics to memorised shortcuts.
