What time is it in London, England, United Kingdom

What time is it in London

London keeps Greenwich Mean Time in winter, UTC+0, and British Summer Time in summer, UTC+1. England does not use a city-only zone. This page shows the live civil hour. The IANA name is Europe/London. In winter the zone abbreviation is GMT. In summer it is BST. The switch follows the United Kingdom’s daylight-saving rule: clocks move forward one hour on the last Sunday in March and back one hour on the last Sunday in October. In 2026 that forward step is 29 March and the return is 25 October. The change is national. Westminster, Greenwich, and Manchester move together.

Greenwich gave the world a meridian and a name for mean time. It did not freeze London on UTC+0 for July. If you convert “London time” in August as if it were GMT, you are an hour early for everyone already on BST. Read the abbreviation on this page, not the word Greenwich alone.

GMT, BST, and the national switch

The winter offset is UTC+0. The summer offset is UTC+1. There is no half-hour, no City of London extra, and no separate zone for Greater London versus the rest of England. Wales and Scotland use the same pair. When you book a call with Johannesburg, which stays on UTC+2, the gap is two hours in British winter and one hour in British summer. When you book with New York, both sides may move, and not on the same Sundays.

The spring-forward happens at 01:00 GMT, which becomes 02:00 BST. The autumn fall-back happens at 02:00 BST, which becomes 01:00 GMT. Overnight jobs, railway engineering, and radio continuity have to name the hour carefully on those two nights. Ordinary weekday meetings should simply be booked after the change date in the new offset.

Winter: GMT, UTC+0, Europe/London. Summer: BST, UTC+1, still Europe/London. Last Sunday in March: forward. Last Sunday in October: back. Do not convert a July London meeting as “GMT” unless the invite truly means UTC.

Greenwich lent the world a meridian. It did not sign a promise that London would stay on winter time in July.

Daylight at England’s latitude

London sits well north of New York and far north of Guangzhou or Nanjing. June evenings run late. December afternoons collapse early. Sunrise and sunset printed for London use this city’s coordinates. They are not interchangeable with Edinburgh’s, which is farther north, or with Greenwich Park versus a western borough in any strict photographic sense, though the civil city uses one pair for ordinary purposes.

BST exists partly so that summer evenings keep civil clock time closer to usable light. It does not create light. After the October change, sunset times on the clock jump later by the hour you just removed, while the sky keeps fading at the same solar moment. People call that “the nights drawing in.” The drawing-in started at the June solstice. The clock change only relabels it.

Civil twilight in midsummer is long. In midwinter it is short and grey. If you need first light for a river photograph, use today’s pair, not a memory of “always 5 a.m. in summer.”

Maritime weather on the London clock

England’s capital has a maritime temperate pattern: mild for its latitude, rain in every season, less heat than Nanjing’s summer and less cold than Changchun’s winter. Weather does not decide GMT versus BST. A warm October week will still fall back on the last Sunday. A cold March week will still spring forward.

Do not paste a New York forecast onto this page because both cities speak English. Do not paste a Johannesburg winter onto a London July because both can look grey on a webcam. The weather here is for London. The hour is GMT or BST according to the date. When the United States is still on daylight time in the first days of November, London has usually already returned to GMT; check both sides that week instead of reusing an October gap.
