United Nations Day
24 October All day
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.
This year is the 75th anniversary of the UN. Learn about the celebrations here. To mark the anniversary, the UN has launched a global conversation on how to tackle the challenges we face and build a better future for all. Join the conversation here #UN75
