The International Day of Peace is observed each year on the opening day of the regular session of the United Nations General Assembly.
Peace is a common desire for peoples throughout the world.
The establishment of the United Nations in 1945, at the end of the most devastating war in human history, was an embodiment of this universal desire. Keeping peace and developing friendly relations among nations are among the main objectives of the United Nations. To commemorate and strengthen the ideals of peace both within and among all nations of the world, the United Nations General Assembly in 1981 proclaimed the opening day of its regular session as the International Day of Peace. In its resolution, the General Assembly invited all Member States, organs and organizations of the UN system, non-governmental organizations, peoples and individuals to observe the Day in an appropriate manner. Although peace is commemorated by various organizations and groups on other dates, the International Day of Peace is the only official commemoration declared by the United Nations.
