The International Day of Peace, sometimes unofficially known as World Peace Day, is observed annually on 21 September. It is dedicated to world peace, and specifically the absence of war and violence, such as might be occasioned by a temporary ceasefire in a combat zone for humanitarian benefit.
The International Day of Peace was established in 1981 by the United Nations General Assembly to coincide with its opening session, which was held annually on the third Tuesday of September. The first Peace Day was observed in September 1982.
This anniversary offers a unique opportunity to reaffirm the United Nations commitment to the purposes and principles upon which the Organization was founded. The Declaration on the Right of Peoples to Peace recognizes that the promotion of peace is vital for the full enjoyment of all human rights.
By creating the International Day of Peace, the UN devoted itself to worldwide peace and encouraged people to work in cooperation for this goal. Since its inception, Peace Day has marked personal and planetary progress toward peace. It has grown to include millions of people worldwide and many events are organized each year to commemorate and celebrate this day.
In 2001, the General Assembly by unanimous vote adopted which established 21 September as an annual day of non-violence and cease-fire.
The United Nations invites all nations and people to honor a cessation of hostilities during the Day, and to otherwise commemorate the Day through education and public awareness on issues related to peace.
