Hindi Divas is an annual day celebrated on 14 September in India to celebrate the popularity of Hindi as an official language of India. Mostly this celebration is a government sponsored event in Central government, but many private organizations and voluntary groups also celebrate the day. 

History

Beohar Rajendra Simha, the acclaimed Hindi-stalwart. On his 50th birthday (14-09-1949), Hindi was adopted as the Official Language of Republic of India, celebrating it as "Hindi-Day" since then.
Hindi Divas is celebrated on 14 September because on this day in 1949, the Constituent Assembly of India had adopted Hindi written in Devanagari script as the official language of the Republic of India. But this didn't come as easily as it sounds. To this end, several stalwarts rallied and lobbied pan-India in favor of Hindi, most notable person Beohar Rajendra Simha along with Hazari Prasad Dwivedi, Kaka Kalelkar, Maithili Sharan Gupt and Seth Govind Das who even debated in Parliament on this issue. As such, on the 50th birthday of Beohar Rajendra Simha on 14 September 1949, the efforts came to fruition following adoption of Hindi as the official language.

This decision was ratified by the Constitution of India that came into effect on 26 January 1950. Under the Article 343 of the Indian Constitution, Hindi written in Devanagari script was adopted as the official language. In all, there are 22 Scheduled languages of India, of which, two are officially used at Union government of India level: Hindi and English. Hindi is spoken by 250 million people as the original language and it is the fourth language of the world.
