Hindi Diwas is celebrated on the 14th of September, to commemorate the adoption of Hindi in Devanagari script as one of the official language of India. Hindi was adopted as one of the two official languages of the Republic of India by Constituent Assembly of India thanks to the efforts of Beohar Rajendra Simha along with Hazari Prasad Dwivedi, Kaka Kalelkar, Maithili Sharan Gupt and Seth Govind Das. As such, on the 50th birthday of Beohar Rajendra Simha on the 14th of September 1949, the efforts came to fruition following the adoption of Hindi as an official language.
