United Nations Day

On 24 October, United Nations Day is celebrated around the world. It is an opportunity to reflect on the organization’s work on behalf of humanity, including on urgent challenges such as alleviating poverty and hunger, defending human rights and addressing the need for bold climate action.

UN Day marks the anniversary of the entry into force in 1945 of the UN Charter. With the ratification of this founding document by the majority of its signatories, including the five permanent members of the Security Council, the United Nations officially came into being.

October 24 has been celebrated as United Nations Day since 1948. In 1971, the United Nations General Assembly recommended that the day be observed by Member States as a public holiday.
