The International Day of Non-Violence is October 2nd, which coincides with Mahatma Gandhi's birthday. The Day was established by a United Nations resolution in 2007, and has the goal to "disseminate the message of non-violence, including through education and public awareness." Visitors to the U.N. website can go to the "Background" link to read a brief summary of Gandhi's philosophy, as well as the definition of non-violence, which includes the three main categories of non-violent action: "protest and persuasion, including marches and vigils", "non-cooperation", and "non-violent intervention, such as blockades and occupations". Visitors interested in reading how the International Day of Non-Violence has been commemorated since 2007 should click on the "Commemoration" link on the left side menu.
