Live times for ~20 major cities worldwide. Plan international meetings by converting any time across every timezone instantly.
A free world clock that shows live, second-by-second times for around 20 major cities worldwide at once, paired with a meeting planner that converts any time and date from your chosen source timezone into every city instantly. It's built for anyone who coordinates across borders and needs to see — at a glance — what time it really is somewhere else.
Every conversion runs through the browser's native IANA timezone database, so daylight saving transitions are handled automatically and you never have to do offset math in your head. People use it to:
Everything is computed local and in-browser from your own device clock — no times, cities, or meeting details are ever sent to a server, so the tool works even offline once the page has loaded.
It reads your device clock and converts it to each city's IANA timezone using the browser's built-in Intl.DateTimeFormat API. Times refresh every second and no external service is contacted.
The clock covers around 20 major cities worldwide spanning every region, but your own location is detected automatically. If your local timezone isn't one of those presets, it's added to the top of the From Timezone dropdown so you can plan meetings from where you actually are.
Enter a proposed time in the planner and scan the converted result for every city at once. Adjust the time up or down until each location lands inside its normal working hours — typically between 9am and 6pm local — and you've found an overlapping slot that suits all participants.
Yes. Because every calculation goes through IANA timezone names rather than fixed offsets, daylight saving is applied automatically for each city on the exact date you choose. That's why picking the meeting date matters — offsets can differ before and after a DST change.
The clock and planner display times in 24-hour format for clarity across regions. To read a time in 12-hour terms, subtract 12 from any hour above 12 — for example 14:30 is 2:30 PM and 21:00 is 9:00 PM.
Set the time, date, and source timezone, then read off each person's converted local time from the results and include it in your invite. For the clearest message, state the time alongside its timezone abbreviation — such as "3:00 PM EST" — so there's no ambiguity.
Yes. A sun icon means the city is currently in daylight hours (6am to 8pm local) and a moon icon means it's night-time. They give you a quick read on whether it's a reasonable hour to reach someone before you check the exact clock.
