"Jana Gana Mana" (Bengali: জন গণ মন, Hindi: जन गण मन) is the national anthem of India. Written in highly Sanskritized (Tatsama) Bengali, it is the first of five stanzas of a Brahmo hymn composed and scored by Nobel laureate Rabindranath Tagore. It was first sung in Calcutta Session of the Indian National Congress on 27 December 1911. "Jana Gana Mana" was officially adopted by the Constituent Assembly as the Indian national anthem on January 24, 1950. 27 December 2011 marked the completion of 100 years of Jana Gana Mana since it was sung for the first time.

The original poem written by Rabinder Nath Tagore was translated into Hindi by Abid Ali. The original hindi version of the song Jana Gana Mana, translated by Ali and based on the poem by Tagore, was a little different. It was "Sukh Chain Ki Barkha Barase, Bharat Bhagya Hai Jaga....". Jana Gana Mana was officially adopted by the Constituent Assembly as the Indian national anthem on January 24, 1950.

A formal rendition of the national anthem takes fifty-two seconds. A shortened version consisting of the first and last lines (and taking about 20 seconds to play) is also staged occasionally. Tagore wrote down the English translation of the song and along with Margaret Cousins (an expert in European music and wife of Irish poet James Cousins), set down the notation at Madanapalle in Andhra Pradesh, which is followed only when the song is sung in the original slow rendition style of singing. However, when the National Anthem version of the song is sung, it is done in the traditional grandiose Martial Style of music, as scored by Captain Ram Singh Thakur in 1943.
