About United Nations Day
United Nations Day is observed on 24 October. It marks the anniversary of the entry into force of the United Nations Charter in 1945, when the United Nations officially came into existence.
The day is useful for explaining the Organization’s founding, Charter purposes and international cooperation without treating every activity of the modern UN system as part of one simple narrative.
Why United Nations Day matters
The United Nations is an international organization created by its Member States under the Charter. Its work spans peace and security, human rights, development, humanitarian action and other areas through different organs, agencies and programmes.
United Nations Day can support civic and historical learning, but institutional claims should still be tied to the relevant UN body or source.
History of United Nations Day
The UN Charter was signed on 26 June 1945 and entered into force on 24 October 1945. United Nations Day therefore marks the Organization’s official founding anniversary.
In 1947 the General Assembly declared 24 October United Nations Day. A later General Assembly recommendation encouraged Member States to observe the day as a public holiday, but that recommendation does not itself establish statutory holiday status in every jurisdiction.
