About this tool
The clock above shows the current local time in London — the UK's capital, sitting on the prime meridian at Greenwich — the reference point the world's time zones are measured from. London keeps GMT / British Summer Time, and this page applies its daylight-saving rules automatically, so the time shown is the time on the wall there today.
Below the main clock you will find the difference between London and your own local time right now, plus the current time in the other major cities — the fastest way to sanity-check a meeting time before you send the invite. All times update every second from the standard time-zone database.
How to use it
- Read the big clock — that is the time in London at this second.
- Check the line beneath it for how far ahead or behind your local time that is.
- Use the city grid to convert the moment across the other major time zones.
Frequently asked questions
What time zone is London in?
London is on GMT / British Summer Time (Europe/London). This page converts using the official IANA time-zone rules, including daylight saving where it applies.
Is London ahead of or behind me?
The page calculates it live and states it under the clock — for example “London is 3 hours behind your local time” — based on both offsets right now.
Why does the difference change during the year?
If either your location or London observes daylight saving and the other does not — or they change on different dates — the gap shifts by an hour for part of the year. The live figure on this page is always the current one.
