How does the Timezone Overlap Finder work?

You add one timezone per team member and optionally set their working hours (default 9 AM–5 PM). The tool converts every person's working hours into UTC, finds the intersection, and highlights that window in green on a shared 24-hour timeline.

Does this tool send my data anywhere?

No. All processing happens entirely in your browser using the built-in JavaScript Intl API. No timezone data, team names, or working hours are ever sent to a server.

What if there is no overlap between timezones?

The tool will show the timeline with no green zone and display a 'No overlap found' message. You can then try adjusting working hours or accept an early/late meeting time.

Can I share the overlap result with my team?

Yes — the 'Copy Best Window' button copies a plain-text summary of the overlapping hours to your clipboard, ready to paste into Slack, email, or a calendar invite.

Does the tool support DST (Daylight Saving Time)?

Yes. The tool uses the browser's native Intl.DateTimeFormat API which respects IANA timezone rules including DST transitions automatically.

How many timezones can I add?

You can add up to 10 timezones. For most remote teams, 3–5 is the sweet spot for readable results.
