World time converter

Add each participant's city (up to six), set one location as the reference, and scan the shared timeline for an hour column where local times look reasonable for everyone. Click a column to lock that moment, then copy the page URL from your address bar so the team opens the same comparison. Shaded weekend and late-night bands help you avoid slots that look fine in one city but fall outside working hours elsewhere.

Yes. This world time converter is free, runs in your browser, and lines up multiple cities on one 24-hour timeline — similar to World Time Buddy for comparing zones and planning calls. No account is required. You can share a URL that restores your cities, reference timezone, and selected datetime.

Search and add each city under Add a city, then read the stacked rows: every row shows the same calendar day in that zone's local time. Click any hour on the reference row to see that instant everywhere. Set a different reference by clicking a row header when you want to think from another team's perspective.

Add New York and London, set New York as the reference, and click the 9 AM column on the timeline (or pick that date and time in the toolbar). The London row shows the matching local time for that exact instant, including daylight saving on the date you chose. Half-hour zones such as India (UTC+5:30) are supported.

Add one city from each region, pick the reference zone that matters most for your anchor (often the host or largest group), and look for hour columns where US afternoon, European evening, and Asia morning overlap. There may be no perfect overlap — use the timeline to see who takes an early or late slot, then share the link with the chosen time.

Yes. When clocks spring forward or fall back, the gap between two cities can shift by an hour even if both use daylight saving. This tool uses IANA timezone data in your browser, so offsets and abbreviations (EST vs EDT, GMT vs BST) update for the date you select. You do not need to look up whether DST is active manually.

Yes. As you work, the address bar encodes your cities, reference timezone, mode (live or fixed), and selected datetime. Copy that URL and send it — teammates open the same side-by-side view without re-entering locations.

No. All time calculations run locally in your browser with Luxon and the IANA timezone database. Cities, dates, and comparisons are not sent to or stored on a server.
