UN Chinese Language Day (United Nations)

UN Chinese Language Day is observed annually on April 20. The event was established by the UN Department of Public Information in 2010, seeking "to celebrate multilingualism and cultural diversity as well as to promote equal use of all six of its official working languages throughout the organization". April 20 was chosen as the date "to pay tribute to Cangjie, a mythical figure who is presumed to have invented Chinese characters about 5,000 years ago".

The United Nations (UN) is the global intergovernmental organization established by the signing of the UN Charter on 26 June 1945 with the articulated mission of maintaining international peace and security, to develop friendly relations among states, to promote international cooperation, and to serve as a centre for harmonizing the actions of states in achieving those goals.

April 20 is the 110th day of the year in the Gregorian calendar; 255 days remain until the end of the year.
