International Day of Peace


International Day of Peace—established by the United Nations General Assembly in 1981 and first observed in 1982—is "devoted to commemorating and strengthening the ideals of peace both within and among all nations and peoples." It was originally held on the third Tuesday of September, which is the opening day of the regular session of the General Assembly. In 2001, a resolution adopted by the General Assembly designated the International Day of Peace to be a "day of global ceasefire and non-violence." It also changed the date of the holiday to September 21.

The holiday has a different theme each year and is marked with education and the raising of public awareness on issues related to peace. The Secretary-General of the United Nations rings the United Nations Peace Bell, which is located in the Peace Garden at the United Nations Headquarters, and a minute of silence is observed. This moment is observed globally at 12:00 noon. The day can be celebrated individually or as part of a group and can be observed by attending various events or programs. It is often marked with intercultural and interfaith dialogues, workshops based on the UN Peace Day theme, vigils, marches, parades, and flag ceremonies.

International Day of Peace, also known as World Peace Day, is observed next on Saturday, September 21st, 2019. It was observed the third Tuesday in September from 1982 until 2001. It has been observed annually on September 21st since 2002.
