Beginning on the 20th anniversary in 2002, the UN General Assembly set 21 September as the now permanent date for the International Day of Peace.
In establishing the International Day of Peace, the United Nations General Assembly decided that it would be appropriate
"to devote a specific time to concentrate the efforts of the United Nations and its Member States,
as well as of the whole of mankind, to promoting the ideals of peace and to giving positive
evidence of their commitment to peace in all viable ways? (The International Day of Peace) should
be devoted to commemorating and strengthening the ideals of peace both within and among all
nations and peoples."
