Find the Best Meeting Time Across Timezones
Visual 24-hour grid. Business-hours overlap highlighted. DST-aware. Up to 8 timezones.
Business hours 09:00–18:00 local. Night 21:00–06:00 local. All offsets use live DST rules.
Scheduling across timezones
Remote teams, cross-border clients, and distributed open-source projects all need a quick way to answer “what time works for everyone?” Manually calculating offsets, remembering which regions are currently on DST, and avoiding the accidentally-scheduled-at-2am mistake is error-prone. This tool makes the overlap immediately visible — green means everyone is at their desk.
