On 25 October 2026, the Canary Islands put clocks back from 02:00 to 01:00. This happens at the same UTC instant as mainland Spain’s change.
The hour repeated in the Canary Islands
The stretch from 01:00 to 01:59 appears twice. A 01:30 appointment needs a first or second occurrence. Choose Santa Cruz de Tenerife as the origin in the converter and select the occurrence when the control appears.
Coordinating with mainland Spain
Madrid remains one hour ahead of Santa Cruz de Tenerife on the comparison dates. A 10:00 Madrid meeting on Monday 26 October is at 09:00 in the Canary Islands. For night-time events, use a fully resolved instant rather than subtracting one hour from memory.
Reading a calendar reminder
The same event is displayed in each device’s configured zone. A reminder showing 02:00 in Madrid after the rollback and 01:00 in the Canary Islands represents one instant, not two separate adjustments.
Common questions
Does “03:00 becomes 02:00” describe the Canary Islands?
That wording describes mainland Spain. In the Canary Islands, 02:00 becomes 01:00.
