This is a day proclaimed by the U.N. each year to promote the ideals of peace. The first official observance of the International Day of Peace was in September 1982. At the United Nations, the day is marked with a special message by the secretary-general, who then rings the Japanese Peace Bell and invites people throughout the world to reflect on the meaning of peace. Special events are organized in various countries, and in the United States the mayors of a number of cities issue proclamations for the day. Discuss
