In 1981, the United Nations General Assembly resolution 36/67 designated the observance of the International Day of Peace, and the first Peace Day was celebrated in September 1982.

In 2001, the General Assembly unanimously voted on resolution 55/8282 designating 21 September as a day of non-violence and cease-fire.
This occasion is an invitation from the United Nations to all nations and peoples to organize events and undertake actions that glorify the importance of peace and democracy in realistic and useful ways.
We, in the Nation Building Movement, celebrate this day as part of our efforts to build peace in Syria, and as support for efforts to achieve peace and stability in the region and the world.
