The first Peace Day was celebrated in September 1982. In 2002 the General Assembly officially declared
September 21 as the permanent date for the International Day of Peace. By creating the International Day of Peace, the UN devoted itself to worldwide peace and encouraged all of mankind to work in cooperation for this goal. During the discussion of the U.N. Resolution that established the International Day of Peace, it was suggested that:

"Peace Day should be devoted to commemorating and strengthening the ideals of peace both within and among all nations and peoples. This day will serve as a reminder to all peoples that our organization, with all its limitations, is a living instrument in the service of peace and should serve all of us here within the organization as a constantly pealing bell reminding us that our permanent commitment, above all interests or differences of any kind, is to peace"

Since its inception, Peace Day has marked our personal and planetary progress toward peace. It has grown to include millions of people in all parts of the world, and each year events are organized to commemorate and celebrate this day. Events range in scale from private gatherings to public concerts and forums where hundreds of thousands of people participate. www.internationaldayofpeace.org
