World Hindi Day is observed annually on January 10 to celebrate the global presence and cultural significance of the Hindi language. The day highlights Hindi's role in connecting people across regions and its evolution in international forums, education, and digital communication. It is distinct from Hindi Diwas, celebrated in India on September 14, which focuses on the language's adoption as an official Indian language. World Hindi Day, first officially observed in 2006, commemorates the first World Hindi Conference in 1975 and emphasizes Hindi's journey beyond national borders.
