Reading your clock…
Seattle changes its clocks twice a year
Standard time is UTC-08:00 and daylight saving time is UTC-07:00. The shift is 1 hour, and it is the reason the distance between Seattle and anywhere else is not a single number.
| Date | Local time | Change | New offset |
|---|---|---|---|
| Sunday, 1 November 2026 | 02:00 → 01:00 | Back 60 min | UTC-08:00 |
| Sunday, 14 March 2027 | 02:00 → 03:00 | Forward 60 min | UTC-07:00 |
| Sunday, 7 November 2027 | 02:00 → 01:00 | Back 60 min | UTC-08:00 |
Same clock, different sky: Los Angeles, San Francisco share America/Los_Angeles. Sunrise and sunset differ between them because latitude does, even though the clock does not.

Daylight in Seattle through the year
From about 8.4 hours in December to 16.0 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 | 07:40 | 16:43 | 9h 3m |
| February | 06:58 | 17:31 | 10h 33m |
| March | 06:04 | 18:13 | 12h 9m |
| April | 05:03 | 18:57 | 13h 54m |
| May | 04:17 | 19:37 | 15h 20m |
| June | 04:02 | 20:02 | 16h 0m |
| July | 04:23 | 19:50 | 15h 27m |
| August | 05:03 | 19:04 | 14h 1m |
| September | 05:44 | 18:03 | 12h 19m |
| October | 06:26 | 17:03 | 10h 37m |
| November | 07:13 | 16:20 | 9h 7m |
| December | 07:45 | 16:11 | 8h 26m |
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 Seattle
What time zone is Seattle in?
Seattle uses the IANA time zone America/Los_Angeles, which is UTC-08:00 in standard time and UTC-07:00 while daylight saving is in force. The same zone covers Los Angeles, San Francisco.
Does Seattle observe daylight saving time?
Yes. Clocks in Seattle move by 1 hour, and the next change is on Sunday, 1 November 2026.
Why does the time difference to Seattle keep changing?
Because the two places do not change their clocks on the same weekend, and in opposite hemispheres they change in opposite directions. London is a clear example: it sits 7 hours ahead, then 8 hours ahead across the year rather than one fixed distance.
How much daylight does Seattle get?
Around 16.0 hours at the longest, in June, and about 8.4 hours at the shortest, in December. The table on this page lists sunrise and sunset through the year. Times are calculated from Seattle's latitude of 47.61° and are approximate to within about an hour for cities that sit well away from the centre of their time zone.
