National cleanup day
September 16, Saturday
National CleanUp Day is held annually in the United States and globally on the third Saturday of September. In the United States, there are cleanups held in every State and Territory. It promotes country-scale organized and individual cleanup events and volunteering to keep the outdoors clean and prevent plastic from entering the ocean. National CleanUp Day is organized by Clean Trails, a nonprofit organization founded by Bill Willoughby and Steve Jewett.
