National Science Day 2026 Date

• National Science Day 2026 Date: 28 February 2026

• First Observed: 1987

• Declared By: Government of India in 1986

• Reason: Discovery of the Raman Effect on 28 February 1928

The History of Science Day

National Science Day in India is celebrated every year on February 28th to honour the remarkable discovery of the Raman Effect by Dr. C.V. Raman in 1928. This day marks the achievement of a groundbreaking contribution to the field of physics, which earned Dr. Raman the Nobel Prize in Physics in 1930.

The idea of observing National Science Day was proposed by Dr. Raman himself, and it was officially recognized by the Government of India in 1986. The primary goal of the day is to promote the importance of science in everyday life and to celebrate the contributions of scientists towards the progress of the nation.

February 28th was chosen as the date for C.V. Raman National Science Day because it was on this day in 1928 that Dr. Raman and his colleagues discovered the phenomenon of scattering of light, known as the Raman Effect. This discovery was crucial in advancing the understanding of light scattering and laid the foundation for many other scientific developments. Dr. C.V. Raman's work continues to inspire generations of scientists, making this day an important occasion to highlight the significance of scientific exploration. This is a significant part of National Science Day history, a day that celebrates the legacy of scientific achievement and encourages innovation and discovery in modern science.

Why is National Science Day Celebrated on 28 February?

National Science Day is celebrated on 28 February because on this day in 1928, Indian physicist Sir Chandrasekhara Venkata Raman announced his discovery of the Raman Effect, which explains how light changes its wavelength when passing through a transparent medium.

This discovery earned him the Nobel Prize in Physics in 1930, making him the first Asian to receive a Nobel Prize in science. To honour this achievement and inspire future scientists, India observes National Science Day every year.
