On March 20, 2011 the organization Stop Street Harassment founded by author Holly Kearl, created the first International Day Against Street Harassment. After only a month of planning, more than 2,000 people from 13 different countries participated in the day of action. It was so successful that it has been extended to a week of events, rallies and protests. This year it's observed from March 18 to 25 with the most events happening on March 24.
