Meeting details
The selected date is the UTC reference date for the candidate hours. Local dates shown for each zone may differ.
Work-hour window
Use local 24-hour times for the regular work window you want to compare.
Time zones
Add the locations you want to compare. Candidate times are evaluated against each selected zone's local work window.
Candidate meeting times
Rows are sorted by full overlap first, then by how many selected zones fit inside the work window.

Time Zone Meeting Planner
Compare local working hours across multiple time zones using a UTC reference date, duration, candidate times, and a copyable or shareable summary.
How this time zone meeting planner works
Add the time zones for everyone in the meeting, choose the date, set the meeting duration, and enter the local work-hour window you want to respect. The planner compares candidate UTC start times against each selected zone.
Date selection matters because daylight saving time can change the relationship between locations. A meeting time that works in March may not map the same way in November.
The guide to DST gaps, repeated times, and date-specific offsets explains why a named zone and date matter for future planning.
Candidate and work-window method
The selected date is a UTC reference date. The planner creates 24 candidates, one at each whole UTC hour from 00:00 through 23:00. For each candidate, the browser formats the same instant in every selected IANA time zone. The browser's time zone data supplies the date-specific offset and daylight-saving rule.
One local work window is applied to every selected zone. A candidate fits a zone when its local start is at or after the window start and its local end, including the meeting duration, is at or before the window end. The window cannot cross midnight. Durations are clamped from 15 minutes to 12 hours. The planner does not check calendars, holidays, weekends, availability, or travel time.
Example: use 2026-01-15, a 60-minute meeting, a 09:00 to 17:00 window, and UTC, New York, and London. The 15:00 UTC candidate displays 15:00 in UTC and London and 10:00 in New York. All three local end times remain within the work window, so the row is marked as fitting all zones.
Impossible dates are rejected. Historical and future results depend on the time zone data available in the browser and operating system. The labels use full IANA identifiers internally, so a short abbreviation is not treated as a globally unique time zone.

When to use it
Use it for remote teams, client calls, interviews, webinars, study groups, international family calls, and planning conversations where several locations need to be considered at once.
This planner is not a calendar app and does not send invitations. It helps compare local times so you can choose a meeting slot and copy a plain summary. A setup link includes the selected date, duration, work window, and time zones. Named presets stay in this browser and are not calendar invitations.
Planner, converter, or world clock
Use the time zone converter when you already have one source time and want to convert it. Use the world clock to see current times. Use this planner when you need to compare a date, duration, work window, and multiple locations.
Once a meeting is scheduled, the meeting timer or meeting agenda timer can help run it.
Accuracy and limitations
Timezone output uses browser-supported timezone data, and daylight-saving rules can change offsets. The selected date is used as the UTC reference date for the candidate hours, so the displayed local calendar date can be earlier or later in another zone.
For critical deadlines, travel, or official scheduling, check the final time with the relevant calendar or local source. UTC is used as the shared comparison point; the UTC clock can help when a schedule is written directly in UTC.

Time zone meeting planner FAQ
Does this account for daylight saving time?
It uses the browser's time zone data for the date you enter, so the selected date is part of the calculation.
Can I add several zones?
Yes. Add the zones you want to compare, remove zones you do not need, and the candidate rows update immediately.
Why do some rows say only part of the group fits?
The row may fall inside the work-hour window for some locations but outside it for others. That can still be useful when there is no perfect overlap.
