Plan a Meeting Across Time Zones Without Date Confusion
Updated 21 October 2026 · Metro Research
“Tomorrow at nine” is not a complete international meeting invitation. Participants need a date, a time zone and enough context to know whether the time falls on the same local day.
Choose a date before comparing times
Offsets can change through the year. A pair of cities may switch daylight saving on different dates, or only one may use it. Metro’s planner uses your browser’s IANA time-zone information for the selected date rather than assuming that every city keeps today’s offset forever.
Keep your browser updated so its time-zone data is current. Where a clock moves forward and a local time does not exist, the planner skips that invalid wall-clock time. Repeated times during a clock change require extra care; confirm the selected instant in the calendar export.
The first city sets the day you browse
In Metro’s planner, the chosen date is the date in the first city. Another participant may see an earlier or later local date for the same instant. Read both the time and the date displayed for each city before selecting a slot.
Working hours are preferences you enter, not proof of anyone’s calendar availability. A city marked inside working hours can still have a holiday, appointment or other conflict. Ask participants to confirm availability.
Check the entire duration
A start time inside someone’s working day may still end after it. The planner checks the selected duration against each participant’s working-hours window. Change the duration if you need a shorter call, then refresh the results.
If there is no overlap, consider a different day, a shorter meeting, asynchronous notes, or a rotation that shares the inconvenience of early and late calls. A green label should help explain a choice, not replace a conversation about a reasonable time.
Share a link with enough context
The meeting link includes your title, selected date, cities, working hours, duration and chosen time. Those settings are in the URL fragment rather than a server-side meeting database. Anyone with the link can read them, so use a neutral title when the link might be forwarded.
Downloading an .ics file gives you a calendar entry using UTC start and end timestamps. Your calendar application can display that instant in its own local time zone. Downloading does not email invitations or add participants automatically.
A final invitation checklist
- Use the actual meeting date and the correct cities.
- Confirm the local date and time for each participant.
- Check duration and practical working hours.
- Open the calendar file and inspect its start and end.
- Share the link or invite using your normal communication channel.
