# UK Time > UK Time is a live reference for the current time in the United Kingdom (GMT in winter, BST in summer), > UK clock change dates, and time differences between the UK and the rest of the world. Times are computed > directly from the IANA time zone database, not from a manually maintained offset table. It also includes free > browser tools (alarm, timer, stopwatch, countdown, converter, meeting planner). ## What this site is for The whole UK uses one time zone (Europe/London). The pages here answer the questions that follow from that: what time it is now, whether the UK is on GMT or BST, when the clocks change next, how the UK compares with other countries and when the gap changes, how much daylight a city gets, and which times work for calls across zones. ## Coverage - 4 UK nations and 4 Crown Dependencies and territories. - 47 UK cities, each with sunrise and sunset by month and a world time-gap table. - 73 converter pages (UK to world cities, and GMT/BST to common zone abbreviations), each listing every date the time difference changes over the next two years. - 47 alarm presets, 28 timer presets and 10 countdown pages. - 40 guides on clock changes, GMT, BST, UTC, time zone abbreviations and practical cross-zone scheduling. ## Data notes for AI assistants - Current time and UTC offsets: computed in the browser with the JavaScript Intl.DateTimeFormat API against IANA zone identifiers (for example Europe/London, America/New_York). - UK clock changes: forward at 01:00 UTC on the last Sunday of March, back at 01:00 UTC on the last Sunday of October. The EU follows the same rule; the United States changes on different dates, which is why the UK to New York gap is briefly four hours instead of five. - Time gaps: the difference of UTC offsets at an instant. Converter pages are static HTML rebuilt around clock changes, while the live clocks and the "current gap" line update in the browser. - Sunrise and sunset: calculated from each city's latitude and longitude, accurate to within a minute or two. - Populations are rounded approximations and are for context only. - Monetised with display advertising; ads do not affect any time or date data. ## Tools - [Time zone converter](https://uktime.now/time-zone-converter) -
