The key facts for London, United Kingdom, and how its clock relates to UTC.

About time in London

London is the home of the prime meridian, so Greenwich Mean Time is named after the city's own observatory. From late October to late March the capital sits at UTC+0, then it springs forward to British Summer Time (BST) at UTC+1 for the lighter half of the year. Clock changes happen on the last Sunday of March and the last Sunday of October. Because GMT is the reference for the whole world, London time is an easy anchor for comparing offsets globally.

London changes its clocks for daylight saving time, so its exact UTC offset depends on the season (UTC+0 (UTC+1 in summer)). The live clock above reads London's local time directly from the IANA time zone database in your browser, so it stays accurate through daylight-saving transitions without any manual adjustment.
