London changes its clocks twice a year
Standard time is UTC+00:00 and daylight saving time is UTC+01:00. The shift is 1 hour, and it is the reason the distance between London and anywhere else is not a single number.
| Date | Local time | Change | New offset |
|---|---|---|---|
| Sunday, 25 October 2026 | 02:00 → 01:00 | Back 60 min | UTC+00:00 |
| Sunday, 28 March 2027 | 01:00 → 02:00 | Forward 60 min | UTC+01:00 |
| Sunday, 31 October 2027 | 02:00 → 01:00 | Back 60 min | UTC+00:00 |
Same clock, different sky: Manchester, Edinburgh share Europe/London. Sunrise and sunset differ between them because latitude does, even though the clock does not.
Time difference from London
Where a range is shown, the gap genuinely changes during the year. That is not rounding or hedging — it is two governments moving their clocks on different weekends.

| Los Angeles | 8 hours behind | −8h / −7h |

Daylight in London through the year
From about 7.8 hours in December to 16.6 hours in June. This is the part a plain clock leaves out: 17:00 is a bright evening in one month and long dark in another.
| Month | Sunrise | Sunset | Daylight |
|---|---|---|---|
| January | 07:54 | 16:28 | 8h 34m |
| February | 07:05 | 17:25 | 10h 20m |
| March | 06:04 | 18:14 | 12h 10m |
| April | 04:55 | 19:05 | 14h 10m |
| May | 04:02 | 19:53 | 15h 51m |
| June | 03:42 | 20:21 | 16h 39m |
| July | 04:07 | 20:06 | 15h 59m |
| August | 04:54 | 19:13 | 14h 19m |
| September | 05:43 | 18:04 | 12h 21m |
| October | 06:32 | 16:57 | 10h 25m |
| November | 07:27 | 16:05 | 8h 38m |
| December | 08:03 | 15:53 | 7h 50m |
Daylight length is accurate. The clock times of sunrise and sunset assume each city sits at the centre of its time zone, which can put them up to about an hour and a quarter out for places near a zone's edge — Madrid being the standard example. Day length is unaffected.
Questions
About time in London
What time zone is London in?
London uses the IANA time zone Europe/London, which is UTC+00:00 in standard time and UTC+01:00 while daylight saving is in force. The same zone covers Manchester, Edinburgh.
Does London observe daylight saving time?
Yes. Clocks in London move by 1 hour, and the next change is on Sunday, 25 October 2026.
Why does the time difference to London keep changing?
Because the two places do not change their clocks on the same weekend, and in opposite hemispheres they change in opposite directions. New York is a clear example: it sits 5 hours behind, then 4 hours behind across the year rather than one fixed distance.
How much daylight does London get?
Around 16.6 hours at the longest, in June, and about 7.8 hours at the shortest, in December. The table on this page lists sunrise and sunset through the year. Times are calculated from London's latitude of 51.51° and are approximate to within about an hour for cities that sit well away from the centre of their time zone.
