About National CleanUp Day

National CleanUp Day is a U.S.-based volunteer cleanup campaign held on the third Saturday in September. Its official site says the first National CleanUp Day was held in 2017.

The organization invites individuals, community groups, businesses and public partners to organize or join cleanups in parks, trails, streets, waterways and other shared spaces.

Why National CleanUp Day matters

The day is about voluntary community stewardship: reducing litter, improving shared outdoor spaces and making cleanup participation easier to organize.

A cleanup campaign does not replace municipal sanitation rules or create authority to enter restricted property. Volunteers should use permitted locations and follow local disposal instructions.

History of National CleanUp Day

National CleanUp Day traces its origin to Steve Jewett and Bill Willoughby, whose trail-cleaning efforts led to the nonprofit Clean Trails.

The official organization says Clean Trails began in 2013 and the first National CleanUp Day followed in 2017.

National CleanUp Day is scheduled for the third Saturday in September; the organizer also supports cleanup activity throughout September.
