When Glasgow changes its clocks
Glasgow is one of the places that still shifts its clocks twice a year
Glasgow keeps Greenwich Mean Time at UTC+00:00 for most of the year, and moves to British Summer Time at UTC+01:00 during its summer. The shift is 1 hour.
Next change
28 March 2027 — clocks move forward by 1 hour, from UTC+00:00 to UTC+01:00.

When the gap to Glasgow 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 Glasgow:
New York (United States)
- From 14 March 2027: Glasgow is 4 hours ahead of New York
- From 28 March 2027: Glasgow is 5 hours ahead of New York
- From 31 October 2027: Glasgow is 4 hours ahead of New York
Dubai (United Arab Emirates)
- From 28 March 2027: Glasgow is 3 hours behind Dubai
- From 31 October 2027: Glasgow is 4 hours behind Dubai
Singapore (Singapore)
- From 28 March 2027: Glasgow is 7 hours behind Singapore

Daylight and the sun over Glasgow
Glasgow sits at 55.87°, -4.26°
Longest day
17h 35m of daylight
Shortest day
6h 59m of daylight
Yearly swing
10h 37m between them
That is a swing of 10h 37m between midsummer and midwinter — a large seasonal difference. In practice it means an afternoon call with Glasgow 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 Glasgow reads 12:00, the sun is not yet overhead — the civil clock runs 17 minutes ahead of mean solar time here.
During summer time that gap widens to 1 hour 17 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
How Glasgow's clock got here
Read from the IANA Time Zone Database, the same rules Linux, macOS and Android use
Glasgow last changed its standard offset 55 years ago, in 31 October 1971, when it moved from UTC+1 to UTC+0 — an hour in a single step.
Every recorded change since 1900
- 27 October 1968UTC+0UTC+1
- 31 October 1971UTC+1UTC+0
When the clocks change here
Clocks go forward on the last Sunday in March, a rule the tzdb has applied since 1981.
It changed once:
- 1981from first Sunday in April to last Sunday in March
Daylight saving began here in 31 October 1971, under a rule set the tzdb calls "GB-Eire". That was 55 years ago.
Before any of this, Glasgow kept local mean time — solar noon by definition — at UTC-0:01, until 1 December 1847. Standard time zones were an attempt to replace that with something people could agree on, and the Glasgow 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.
