Europe's clocks go back on 25 October: check country and time zone
Prepared with AI assistance; sources and original commentary are identified.
Official UK and Dutch calendars indicate a one-hour rollback on 25 October 2026. The local transition time differs: 2am in the UK and 3am in the Netherlands. Check the appointment's location before adjusting your calendar. [1] [2]
In the UK, the transition is at 2am local time
GOV.UK lists 25 October as the date clocks go back in 2026. British guidance specifies moving back one hour at 2am on the last Sunday in October: the clock therefore goes from 2am to 1am. The summer period is known as British Summer Time, or BST; after the rollback, the reference is Greenwich Mean Time, or GMT. The official page already lists the 2026 calendar, although its stated last update was in November 2025. This is calendar guidance, rather than an announcement of a new rule this week. [1]
In the Netherlands, the local reference is 3am
The Dutch government says clocks go back one hour at 3am on Sunday 25 October 2026, taking them to 2am. Its document explains that summer time was aligned with practices in neighbouring countries and cites Directive 2000/84/EC as the basis for its start and end. Comparing this with the British calendar shows why a headline saying only that the change happens at two in the morning can confuse international readers. When organising a journey or meeting, identify the country and local time stated by the relevant source. [2] [1]
Automatic adjustment depends on the device and time zone
The National Physical Laboratory explains that UTC remains the reference: the seasonal transition changes the display of civil time, without adding or removing an hour from UTC. It also distinguishes synchronising a clock over the internet using NTP from consulting the rules that determine when to change the displayed time. Manufacturers and software suppliers use their own programs for this task. Do not assume every device will adjust in the same way. As a practical precaution, check the device's time zone and automatic options, without pre-empting an adjustment the system may already perform. [3]

GOV.UK — When do the clocks change?
Claims supported:
- UK: clocks go back on 25 October 2026 at 2am local time; the page explains BST/GMT and lists its last update.
Government of the Netherlands — Why do the clocks change twice a year?
Claims supported:
- Netherlands: clocks move from 3am to 2am on 25 October 2026; the page cites Directive 2000/84/EC.
National Physical Laboratory — When do the clocks change?
Claims supported:
- UTC is not seasonally adjusted; NPL distinguishes NTP synchronisation from local time rules and describes manufacturers' implementations.
Editorial commentary
Our editorial view is that useful guidance combines the date, country and local reference. These two official examples avoid suggesting that one transition time applies to every European clock. For anyone arranging a meeting, we recommend also recording its city and checking how the application represents that time zone. This is an organisational recommendation, rather than confirmation of how a particular application works. [1] [2]
We also recommend checking separately whether the clock is synchronised and whether its time-zone rule matches the location. NPL's distinction helps frame those questions, but this article reports no tests of phones, systems or calendars performed by us. The cover is an AI-generated conceptual scene. The sources below let readers check the original guidance without relying on the illustration or a generic claim about automatic adjustment. [3]
