Calendar-safe handoff
Need a checklist before inviting the team? Read the timezone meeting planning guide for overlap windows, shared calendar links, and daylight-saving-safe scheduling.
The calendar handoff uses America/Los_Angeles as the base timezone. Keep the IANA zone with the invite so daylight saving changes are recalculated by the calendar, not guessed from a fixed offset.
Copy the meeting text before sending links. It gives attendees the local-time audit trail, offset labels, and work-hour warnings behind the selected instant.
For repeats, create the recurrence in your calendar with the same timezone and re-open this planner around DST boundaries to confirm the burden has not shifted unfairly.
Scheduling FAQ
Choose the cities or IANA time zones, compare the fair score for candidate windows, then pick a time that keeps the burden away from the same participant every week.
The fair score summarizes how well a proposed window fits local working hours across all selected cities, so you can quickly spot balanced times instead of optimizing for only one office.
After selecting cities and a meeting date, review each local time row to identify participants who would be before or after normal working hours before you copy or send the invite.
Daylight saving time can change UTC offsets on different dates in different countries. Keep calendar invites tied to real IANA time zones, not fixed offsets, and re-check the meeting date.
Yes. The planner accepts cities, time zone, and date query parameters for prefilled planning while the canonical page remains the clean /meeting URL.
Copy the selected meeting details after checking the date, city list, and DST-aware local times, then create the calendar invite with named time zones so Google Calendar, Outlook, and ICS files do not drift.
