Trick-or-treat hours vary depending on where you live and how old the kids are. Generally, trick-or-treating begins around sunset or earlier for the youngest set, while older children, pre-teens, and teens will arrive by 8 p.m. or 9 p.m., or the time stated by local curfew laws. According to popular polling, trick-or-treating typically ends around 9 p.m. each Halloween for older kids, with younger kids tiring out at around 8 p.m. . However, the exact start and end times of trick-or-treating can vary depending on the city or town. For example, some areas kick off door-to-door trick-or-treating at 3:30 p.m., while others start as late as 6:30 p.m. . Its best to check your local news outlets or community forums for the most accurate trick-or-treat times in your area.
