About Chinese Language Day
Chinese Language Day is a United Nations language observance held on 20 April as part of the UN’s programme celebrating its six official languages.
The day is designed to support multilingualism, cultural diversity and more balanced use and appreciation of the UN’s official languages within the organization.
Why Chinese Language Day matters
Language Days at the United Nations are not national-language rankings. They are a structured multilingualism initiative in which each of the six official UN languages has its own observance.
Chinese Language Day combines language and cultural programming with a date linked to Guyu, a traditional solar term associated in legend with Cangjie and the invention of Chinese characters.
History of Chinese Language Day
On 19 February 2010, the United Nations Department of Public Information announced the launch of Language Days at the United Nations for all six official languages.
The original launch notice had not yet fixed the Chinese date. Current UN material uses 20 April and explains that the date was selected from Guyu to pay tribute to Cangjie.
The reviewed sources establish the initiative and current date rationale but do not identify the first exact Chinese Language Day observance strongly enough to assert it.
