Timezone Meeting Planner
Compare one meeting time across organizer and attendee time zones with work-hours guidance.
Enter a proposed meeting time and the time zones your attendees use. The planner converts the same instant for each location, flags times outside your chosen working window, and suggests nearby slots that may fit more people.
Use the calendar date as seen by the organizer.
Choose the proposed start time in the organizer time zone.
Choose an IANA time zone from the browser-supported list.
Used for work-hours checks and the summary. Keep it between 1 minute and 24 hours.
Enter one time zone per line. Optional labels can use "Label | Time/Zone". Commas and semicolons also separate entries.
Earliest local start time counted as inside working hours.
Latest local ending time counted as inside working hours.
How far before and after the proposed time to look for alternatives.
Spacing between suggested alternate start times.
How it works
The planner treats the organizer date, time, and time zone as one proposed meeting instant. It then shows the matching local date and time for each attendee time zone and notes whether the meeting fits the configured working window.
Nearby alternatives are scored by how many attendee locations fit the working window. The suggestions are intentionally practical rather than authoritative: they help spot better windows, but they do not know holidays, personal calendars, travel schedules, or local team agreements.
Time zone rules change over time and daylight-saving transitions can create skipped or repeated local times. If a proposed local time is not valid in the organizer time zone, choose a nearby valid time and recalculate.
