Hindi Day is observed in India every September 14, commemorating the adoption of Hindi as the official language of the Dominion of India. This day marks the recognition of Hindi, one of the two standardized forms of the Hindustani language, alongside Urdu. Hindi is primarily spoken by the Hindu community and utilizes the Devanagari script, incorporating a significant number of Sanskrit words, while Urdu is associated with the Muslim community and employs the Persian alphabet with more Persian and Arabic vocabulary. The significance of Hindi Day stems from the decision made by the Constituent Assembly on September 14, 1949, to designate Hindi as the official language of the government, although India does not have a national language. The celebration of Hindi Day highlights the cultural importance of the language and its role in unifying the diverse linguistic landscape of India.
