When the gap to Windsor 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 Windsor:
London (United Kingdom)
- From 14 March 2027: Windsor is 4 hours behind London
- From 28 March 2027: Windsor is 5 hours behind London
- From 31 October 2027: Windsor is 4 hours behind London

Shortest day
9h 05m of daylight
Yearly swing
6h 12m between them
That is a swing of 6h 12m between midsummer and midwinter — a large seasonal difference. In practice it means an afternoon call with Windsor 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
When the clock in Windsor reads 12:00, the sun is not yet overhead — the civil clock runs 32 minutes ahead of mean solar time here.
During summer time that gap widens to 1 hour 32 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
How Windsor's clock got here

When the clocks change here
Clocks go forward on the second Sunday in March, a rule the tzdb has applied since 2007.
It has changed several times:
- 1987from last Sunday in April to first Sunday in April
- 2007from first Sunday in April to second Sunday in March
Before any of this, Windsor kept local mean time — solar noon by definition — at UTC-5:18, until 1895. Standard time zones were an attempt to replace that with something people could agree on, and the Windsor clock still carries the residue of that original figure.
Every date above is a record in the IANA Time Zone Database, not an estimate. The database is maintained by volunteers who track official announcements; if a government changes its rules, these figures change with it.
