Mainland Portugal and the autonomous regions of Madeira and the Azores will set their clocks back one hour next morning, to begin winter time.
In the early hours of Sunday (October 27), in mainland Portugal and the Autonomous Region of Madeira, when it is 02:00, the clocks must be turned back 60 minutes, to 1:00.
In the Autonomous Region of the Azores, the change will be made at 1am on Sunday, moving to 0am.
The legal time will then change again on March 30, 2025, to the summer regime.
The current time change regime is regulated by a directive (community law) from 2000, which provides that every year clocks are, respectively, moved forward and backward by one hour on the last Sunday in March and the last Sunday in October, marking the start and end of daylight saving time.
