Building Back Together for Peace and Prosperity

A symbol of hope for global unity

United Nations Day, on 24 October, marks the anniversary of the day in 1945 when the UN Charter entered into force. UN Day, celebrated every year, offers the opportunity to amplify our common agenda and reaffirm the purposes and principles of the UN Charter that have guided us for the past 76 years. Usually held in the General Assembly Hall of the Organization, at Headquarters in New York, a concert is held to mark UN Day.  As the world begins gradually to recover from the Covid-19 pandemic, the 2021 Concert represents a call to strengthen international cooperation in the interest of both nations and peoples, for a more peaceful and prosperous future for all.

Hymn to the United Nations

Get inspired by this revived W.H. Auden’s Hymn to the United Nations. "Let music for peace Be the paradigm, For peace means to change At the right time, As the World-Clock, Goes Tick and Tock. So may the story Of our human city Presently move Like music, when Begotten notes New notes beget, Making the flowing Of time a growing".

How it all started

In 1945, representatives of 50 countries met in San Francisco at the United Nations Conference on International Organization to draw up the United Nations Charter. The United Nations officially came into existence on 24 October 1945, when the Charter had been ratified by a majority of signatories.

International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
