After Mandarin Chinese and English, Hindi has over 600 million native speakers making it the third most widely spoken language in the world. With pride, World Hindi Day is observed on January 10 every year. It commemorates the day in 1949 when Hindi was first used in the General Assembly of the United Nations and is also referred to as Vishwa Hindi Diwas.

The first World Hindi Day was observed on January 10, 2006, at the initiative of former prime minister Dr. Manmohan Singh. In 1950, Hindi became India's official language.

On World Hindi Day, Hindi is celebrated as a worldwide language. The purpose of the Hindi Diwas is to raise awareness of both the use of the Indian language and the persistent problems with its promotion and usage. It also emphasizes strongly the importance of fostering a love of the language and respecting the contributions of Hindi speakers.

The Indian government also organizes a conference to promote Hindi. The first meeting, known as the "World Hindi Conference," took place in Nagpur in 1975. The conference was attended by 122 representatives in total from 30 countries. This year, the Ministry of External Affairs will work with the Government of Fiji to conduct the 12th World Hindi Conference in Fiji from February 15–17.

The primary theme of the conference celebrating World Hindi Day in 2023 is "Hindi: From Traditional Knowledge to Artificial Intelligence." The Denarau Island Convention Center in Nadi, Fiji, will host the conference. According to a statement on the World Hindi Conference's official website, several exhibitions connected to the growth of the Hindi language will be organized at the conference location.
