Hindi Diwas is celebrated annually on September 14th in India to honor the adoption of Hindi as one of the official languages of the country. On this day in 1949, the Constituent Assembly of India recognized Hindi, written in the Devanagari script, as the official language of the Republic of India. The celebration aims to promote and preserve the Hindi language, which is widely spoken across the country.

Hindi Diwas serves as a reminder of the cultural significance of the Hindi language and encourages people to use it in daily communication, literature, and official work. Various educational institutions, government offices, and organizations conduct events such as essay competitions, debates, and cultural programs to celebrate the day.

It highlights the diversity of languages in India while emphasizing the importance of Hindi as a unifying language among the many languages spoken in the country.
