Scheduling across regions
Find shared working windows across two to five time zones when schedule fairness matters more than a single headquarters clock.
Calculator
Choose the date, define the local workday range, add the relevant time zones, and let the tool surface the best overlap.
Method
The algorithm scans 30-minute slots across a day in UTC, maps each slot into selected local zones, and counts how many zones are within the defined workday range.
It returns full overlap windows or the best partial windows when full overlap is impossible.
Limitations: the result does not account for personal availability, calendar conflicts, local holidays, or organization-specific meeting policies.

The tool returns best partial windows and indicates how many zones are covered.
Between 2 and 5 unique zones.
Yes. Time-zone conversion uses date-aware offsets.
Add all relevant zones, set the workday range, and the tool will surface the longest window where all participants are within working hours.
That depends on the agenda, but most teams find 30 minutes too short for discussion. Aim for at least a 60-minute shared window when possible.
Re-run the overlap finder after each DST change, since the shift can move or eliminate a shared window that previously worked.
