India's National Anthem was reportedly first sung at the Calcutta session of the Indian National Congress in December 1911
The original was written in Bengali and the full song has 5 stanzas.
The text of the national anthem was first published in 1905, in an issue of Tatwabodhini Patrika.
The song was translated into English in 1919 with the title "Morning Song of India"
It was labelled 'national anthem' by Netaji Subhas Chandra Bose for the first time during the meeting of the German-Indian Society on September 11, 1942. However, it formally became the anthem in 1950.
It takes approximately 52 sec to sing the national anthem in its entirety, not beyond that.
The hindi version of the national anthem was adopted by the Constituent Assembly on January 24, 1950.
Netaji Subhash Chandra Bose was a key person in making the selection of the national anthem.
There is also a Hindi-Urdu version by Captain Abid Hasan Safrani, titled 'Subh Sukh Chain'
