Current time in major cities worldwide, updated every second.
World clock — current time in major cities
The page displays the current local time in eight cities across every major inhabited time zone, updated every second using your browser's built-in Intl.DateTimeFormat API. No external time-server requests are made — the reference clock is your device's own system time. UTC offsets are shown beneath each city and reflect daylight saving rules automatically.
Because the page relies on Intl rather than a fixed offset table, transitions into and out of daylight saving time are handled correctly for every zone without any special-case code.
FAQ
Is the time accurate? Yes, to within a second of your device's system clock. If your device's clock is correct (it is synchronized by NTP on virtually all modern operating systems), the displayed times are correct.
Why do some offsets show half-hours? Several regions use non-whole-hour UTC offsets. India (UTC+05:30), Nepal (UTC+05:45), and parts of Australia are common examples. The offset shown reflects the actual rule for each zone.
