National CleanUp Day

National CleanUp Day is held annually in the United States and globally on the third Saturday of September. It promotes country-scale organized and individual cleanup events and volunteering to keep the outdoors clean and prevent plastic from entering the ocean.
The website https://www.nationalcleanupday.org/ provides information about National CleanUp Day and how to participate in it. The website has a list of events that are happening across the United States and globally, which can be filtered by state or country. The website also provides resources for organizing a cleanup event, such as a guide for organizing a cleanup event, a list of cleanup supplies, and a list of frequently asked questions.
It unites 191 countries across the world for a cleaner planet.
