The International Day of Peace is celebrated on September 21, 2020. It is also known as the World Peace Day and occurs annually on September 21. The day is dedicated to peace, and specifically the absence of war, such as might be occasioned by a temporary ceasefire in a combat zone. The World Peace Day was declared by the United Nations (UN) in 1981. Since then it is observed by many nations, political groups, military groups, and peoples.
To inaugurate the International Day of Peace, the "Peace Bell" is rung at UN Headquarters. The bell is cast from coins donated by children from all continents. It was given as a gift by the United Nations Association of Japan, and is referred to as "a reminder of the human cost of war." The inscription on its side reads: "Long live absolute world peace." Individuals can also wear White Peace Doves on this day to commemorate the International Day of Peace, which are badges in the shape of a dove produced by a non-profit in Canada.
Peace is a state of harmony characterized by the lack of violent conflict. Commonly understood as the absence of hostility, peace also suggests the existence of healthy or newly healed interpersonal or international relationships, prosperity in matters of social or economic welfare, the establishment of equality, and a working political order that serves the true interests of all. In international relations, peacetime is not only the absence of war or conflict, but also the presence of cultural and economic understanding and unity. (With material from: Wikipedia)
