It was originally composed as Bharoto Bhagyo Bidhata in Bengali by poet Rabindranath Tagore . The first stanza of the song Bharoto Bhagyo Bidhata in its Hindi version was adopted by the Constituent Assembly of India as the National Anthem on 24 January 1950 . A formal rendition of the national anthem takes approximately fifty - two seconds . A shortened version consisting of the first and last lines (and taking about 20 seconds to play) is also staged occasionally . It was first publicly sung on 27 December 1911 at the Calcutta (now, Kolkata) Session of the Indian National Congress . This is the first of five stanzas of Tagore's Bengali song Bharoto Bhagyo Bidhata . </P> <P> The poem was first sung on the second day of the annual session of the Indian National Congress in Calcutta on December 27, 1911, and again in January 1912 at the annual event of the Adi Brahmo Samaj . Though the Bengali song had been written in 1911, it was largely unknown except to the readers of the Adi Brahmo Samaj journal, Tattwabodhini Patrika, of which Tagore was the editor . </P>
