While the formal rendition of 'Jana Gana Mana', which is written in Bengali Sanskrit, takes 52 seconds, a shorter version takes approximately 20 seconds. The shorter version includes the first and last lines of the National Anthem and is played on certain occasions. Composed by Rabindranath Tagore, 'Jana Gana Mana' was officially declared India's National Anthem on January 24, 1950.
