Find the overlap in working hours (9:00–17:00) across two or three time zones.
Scheduling across time zones
The planner converts each zone's 9:00–17:00 business day to UTC and intersects them, then translates the shared window back to each participant's local clock. Offsets come from your browser's IANA time-zone database, so daylight saving is handled automatically. For a specific city's current time, see our live city clocks.
Frequently asked questions
Does it handle daylight saving?
Yes — offsets are read live from the browser's time-zone database for today's date.
Can I use custom working hours?
This version fixes 9:00–17:00; shift the result mentally for earlier or later days.
Why is there no overlap?
Zones more than 8 hours apart share no standard business window — one side must flex.
