世界時計
Put the current time of multiple cities on one screen, so you can see at a glance "what time is it for them" before a cross-border meeting or remote collaboration. Each city gets a round analog dial with live hour, minute and second hands, labeled with the city name and time zone; offsets auto-adjust for daylight saving by the current date.
There are 38 standard time zones in the world (counting distinct UTC offsets actually in use in 2026, from UTC−12 to UTC+14, including non-hour offsets like UTC+05:30 and UTC+05:45); if you also count daylight-saving shifts the number is about 50 per year, and the IANA database lists about 345 geographic zones. Below, all 38 zones are listed in UTC order with at least one major city each, and multiple important cities in a zone are listed together.
All computation happens on your device.

FAQ
Why is a city's offset different from last time I looked?
Cities with daylight saving move the clock forward an hour in certain months, so the offset changes; the page handles it automatically.
