How to use this calculator
Set a meeting date, define each participant's workday in their own time zone, and review the overlap length and suggested start times.
Set each participant's working hours and time zone
Enter Participant A and B's local working window start and end times alongside their respective time zones. Use the IANA zone names (e.g. America/New_York, Europe/Berlin) for accuracy.
Enter the required meeting duration
Type the meeting length in minutes. The tool checks whether the overlap window is long enough to accommodate it and flags when there is no viable slot.
Review the overlap and suggested slots
The result shows the shared availability window in both local times, the overlap length, and the list of possible meeting start times that fit the required duration.
