International Day of Peace
In 1999 Jeremy Gilley desired there be one single day when all countries vowed not to wage war: a worldwide ceasefire and day of non-violence. He established Peace One Day. The United Nations had already declared the third Tuesday of September the International Day of Peace, Peace One Day aimed to resolve the confusion on which calendar day it fell, and on 7 September 2001, the United Nations General Assembly unanimously adopted a resolution formally establishing the UN International Day of Peace an annual Peace Day of global ceasefire and non-violence on 21 September.
