Each year, September 21 marks Peace Day — a day for wide-scale community action, and a day for United Nations agencies and aid organizations to safely carry out life-saving work. By 2007, 100 million people were active on Peace Day. On Peace Day 2008, the U.N. Department for Safety and Security recorded a 70% reduction in violent incidents in Afghanistan.
For Peace Day 2012, there is an initiative to have all sectors of society observe a day of Global Truce.
…individuals in every country, at home, in schools, in the workplace, in our local communities, and those engaged in armed conflict on the international stage. Everyone has a role to play.
