Planet Fitness closing times vary by location, but many gyms operate from early morning around 5:00 am until late evening or midnight on weekdays, and earlier closing times on weekends (often around 8:00 pm). Some locations are open 24 hours, but others have reduced hours, especially due to staffing and management decisions. On major holidays, Planet Fitness often closes early or is closed entirely, such as on Thanksgiving and Christmas. For example, closing times on these holidays can range from early evening (around 5:00 pm to 10:00 pm), and some days like Thanksgiving and Christmas are full closures. Because Planet Fitness gyms are franchise-operated, hours can differ significantly by gym, so it's best to check with a specific local gym for its exact closing time.
