When the gap to Groningen changes
Dates in the next year where the difference shifts, by counterpart city

New York (United States)
- From 14 March 2027: Groningen is 5 hours ahead of New York
- From 28 March 2027: Groningen is 6 hours ahead of New York

Yearly swing
9h 28m between them

Clock time versus solar time
When the clock in Groningen reads 12:00, the sun is not yet overhead — the civil clock runs 34 minutes ahead of mean solar time here.
During summer time that gap widens to 1 hour 34 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
How Groningen's clock got here
Read from the IANA Time Zone Database, the same rules Linux, macOS and Android use
Groningen last changed its standard offset 86 years ago, in 20 May 1940, when it moved from UTC+0 to UTC+1 — an hour in a single step.
Every recorded change since 1900
- 8 November 1914UTC+0UTC+1
- 11 November 1918UTC+1UTC+0
- 20 May 1940UTC+0UTC+1
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 1 May 1916, under a rule set the tzdb calls "C-Eur". That was 110 years ago.
Before any of this, Groningen kept local mean time — solar noon by definition — at UTC+0:18, until 1880. Standard time zones were an attempt to replace that with something people could agree on, and the Groningen 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.
