National Mathematics Day: Why is it celebrated on Srinivasa Ramanujan’s birthday?

National Mathematics Day is marked on December 22, the birthday of Srinivasa Ramanujan, whose work still amazes the world. But the day isn’t only about remembering a genius. It is also a reminder that maths powers modern life — from science and tech to money, medicine and policy — and that students should learn to enjoy reasoning and patterns, not just chase marks.
