The day marks the birth anniversary of Srinivasa Ramanujan (1887–1920), a legendary Indian mathematician.
The Government of India declared the Day in 2011.
The day aims to encourage students to take an interest in mathematics and promote scientific thinking and problem-solving skills.
India has a rich mathematical tradition, including the invention of zero, the decimal system, and early ideas of negative numbers.
Ramanujan has made some major contributions to number theory, infinite series, continued fractions, and mathematical analysis, influencing modern research in mathematics, physics, and computer science.
