Answer: 14 September
Notes: Hindi Diwas, celebrated on September 14, honors Hindi as one of India’s official languages. This date marks the anniversary of the 1949 decision by India’s Constituent Assembly to adopt Hindi in Devanagari script as the official language. The celebration has roots in the 1918 formation of the Hindi Sahitya Sammelan, which advocated for Hindi as a national language. The first Hindi Diwas was observed in 1953, and it aims to promote Hindi and unite India's diverse linguistic and cultural regions. In 2024, Hindi Diwas falls on Saturday, September 14.
