National Science Day is observed every year on February 28 to commemorate the discovery of the 'Raman Effect'. On this day, the great Indian scientist, CV Raman, invented the 'Raman Effect' and won the Nobel Prize in the year 1930. The government of India honoured him with the Bharat Ratna in the year 1954.

 

In recognition of this discovery, the National Council for Science and Technology Communication (NCSTC) proposed that National Science Day be celebrated on February 28 each year. As a result of that proposal, the Indian Government accepted it, and the first National Science Day was celebrated on February 28, 1987.
