When Seattle changes its clocks

When the gap to Seattle changes
Dates in the next year where the difference shifts, by counterpart city
The difference between two cities is not a constant. It changes whenever either side moves its clocks — and because regions switch on different dates, there are short windows each year when the usual gap is wrong. These are the dates that matter for Seattle:
London (United Kingdom)
- From 25 October 2026: Seattle is 7 hours behind London
- From 1 November 2026: Seattle is 8 hours behind London
- From 14 March 2027: Seattle is 7 hours behind London
- From 28 March 2027: Seattle is 8 hours behind London
Frankfurt (Germany)
- From 25 October 2026: Seattle is 8 hours behind Frankfurt

Daylight and the sun over Seattle
Seattle sits at 47.61°, -122.33°
Longest day
15h 59m of daylight
Shortest day
8h 25m of daylight
Yearly swing
7h 34m between them
That is a swing of 7h 34m between midsummer and midwinter — a large seasonal difference. In practice it means an afternoon call with Seattle lands in broad daylight in June and well after dark in December, even though the clock time has not moved.
Clock time versus solar time
Seattle's clock is unusually well matched to the sun: local noon falls within 9 minutes of the moment the sun is actually overhead. Most cities sit further out, because time zones follow borders rather than longitude.
During summer time that gap widens to 1 hour 9 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
