The International Day of Peace was established in 1981 by the United Nations General Assembly.
Two decades later, in 2001, the General Assembly unanimously voted to designate the Day as a period of non-violence and cease-fire.
The Peace Bell was donated by the United Nations Association of Japan in 1954. It has become tradition to ring the bell twice a year: on the first day of spring, at the Vernal Equinox, and on 21 September to celebrate the International Day for Peace.
