On Sunday morning (October 30) in mainland Portugal and the Autonomous Region of Madeira, at 02:00 the clocks must be set back 60 minutes, passing to 01:00.

In the Autonomous Region of the Azores, the change will be made at 01:00 am on Sunday, moving to 00:00.

The current time change is regulated by a directive (community law) of 2000, which provides that each year clocks are, respectively, set forward and back one hour on the last Sunday in March and on the last Sunday in October, marking the start and end of daylight-saving time.
