The International Day of Peace ("Peace Day") is observed around the world on 21 September.

Established in 1981 by unanimous United Nations resolution, Peace Day provides a globally shared date for all humanity to commit to Peace above all differences and to contribute to building a Culture of Peace.

The UN General Assembly has declared this as a day devoted to strengthening the ideals of peace, through observing 24 hours of non-violence & cease-fire.
