Hindi Diwas is celebrated on September 14 every year to honor the adoption of Hindi, written in the Devanagari script, as the official language of India. This decision was made on September 14, 1949, by the Constituent Assembly of India, recognizing Hindi's importance as a unifying language in a country with many languages and dialects. The day promotes the use of Hindi in daily life and fosters national pride and unity by celebrating the cultural and linguistic heritage of Hindi. It also highlights Hindi's role in preserving ancient texts and adapting to modern demands, ensuring its rich heritage continues to thrive. The celebration encourages people to embrace Hindi as a crucial part of India's identity and unity, with many cultural programs held in schools, colleges, and public institutions. The first Hindi Diwas was celebrated in 1953, and the date was chosen by India's first Prime Minister Jawaharlal Nehru, coinciding with the birthday of the Hindi scholar Beohar Rajendra Simha.
