How does the time overlap finder work?

It checks candidate meeting times against each selected city's local working hours and ranks the slots where the most cities are available.

Does this handle daylight saving time?

Yes. Times are formatted with IANA time zones through the browser Intl API, so daylight saving rules are applied for the selected date where supported.

Can I change working hours?

Yes. You can set a custom workday start and end time, then the tool recalculates the overlap instantly.

Is my meeting data uploaded?

No. The calculation runs in your browser. DateToolsHub does not upload or store the selected cities, dates, or times.
