Time Zone Planner — Find meeting overlap across time zones — OnePassApps
Compare working hours in two to eight time zones, see the shared overlap and share a meeting time as text or a downloadable .ics file.
Time Zone Planner lines up working hours in two to eight places so you can see when everyone is available. Pick a date, set each place's hours, read the shared overlap, then convert one meeting time to every local time. Offsets come from your browser's own time zone data. Your plan stays in this tab and needs no account.
What you can do
- Search the browser's time zone list by city or zone name and see each place's UTC offset and abbreviation for the chosen date.
- See 24-hour strips aligned to a reference place, with working hours and the shared overlap highlighted, including overnight hours.
- Convert one meeting slot to every place's local time and day, then copy a text summary or download an .ics file.
Limitations
- Plans hold two to eight places, dates from 1970 to 2100 and meetings from 5 minutes to 24 hours. Each place has one daily working window.
- There are no recurring events, attendees, reminders or holiday data. Offsets rely on your browser's time zone database, so an out-of-date browser may disagree with very recent rule changes. Reloading clears the plan.
Is Time Zone Planner free, and do I need an account?
Yes, it is free. Time Zone Planner runs in your browser with no account or payment details, and it never uses OnePassApps credits.
