In honour of the great Indian mathematician Srinivasa Ramanujan's birth date, December 22 is recognised as National Mathematics Day each year. He is credited with making significant contributions to mathematical analysis, infinite series, number theory, etc. To honour his contributions and remember him as a math genius, Mathematics Day is observed.

Ramanujan enrolled at Trinity College and was selected as one of the London Mathematical Society's members. He was elected as a fellow of the Royal Society in 1918. Ramanujan was also nominated as the first Indian to be a Trinity College Cambridge fellow member. His works were recognized by British mathematicians like G.H. Hardy, who was spellbound by his knowledge of advanced mathematics.

In 2012, the Ex-Prime minister Dr. Manmohan Singh designated this day as National Mathematics Day to pay tribute to the legendary Srinivasa Ramanujan.

Mathematics commonly known as Maths plays a key role in understanding all sorts of subjects like science, music, social studies and art and so on. The study of mathematics aids in improving problem-solving abilities and promotes organisation and logical thought in people.

Mathematics Day is marked to raise awareness about the key role of mathematics. People celebrate this day to realsie how maths is important for developing humanity from the grassroots level.  The aim of Mathematics Day is to recognise and appreciate all that this field of study has to give to both individuals and to the world at large.

The National Academy of Science India holds workshops to celebrate the day. Every year, various noted lecturers and mathematicians from all over the world attend this workshop. On Maths Day, the speakers also talk about the contributions of Srinivasa Ramanujan to the world of mathematics at the national and international levels.
