Every year 10th January is celebrated as World Hindi Day to create awareness about the language of Hindi across the World and to present Hindi as an international language. The first world World Hindi Conference was organized in Nagpur on January 10, 1975. The conference saw representation from 30 countries. To commemorate the occasion, the government of India since 2006 is celebrating 10th January as World Hindi Day.
Every year Hindi Divas is celebrated on September 14th because it was the day Hindi was recognized as an official language. On 14 September 1949, the constituent assembly adopted Hindi written in Devanagari script as the Official Language of the Union. While the World Hindi Day is aimed at the promotion of the Hindi language at the global stage, the Hindi Divas is being observed across the country at the national level.
Hindi is the fourth most spoken language of the world. Various constitutional provisions like Article 120, Article 210, Article 343, Article 344 and Articles from 348 to 351 are aimed at the promotion of Hindi.
