London Time: Live World Clock

This page opens the world clock with London already added to the card list, alongside the tool’s own defaults: your browser’s time zone, UTC, New York, and Tokyo. London’s current time, date, and UTC offset are visible the moment the page loads.

London observes British Summer Time for part of the year, so its offset from UTC shifts between UTC+0 and UTC+1 depending on the date — a detail that trips up quick mental math and is exactly what a live clock settles instantly.

Every card updates once a second, and you can add any other IANA time zone your browser supports using the selector below the list — useful for comparing London against a call, a flight, or a deadline in another city at the same time.
