The EU Commission is proposing to end the practice of adjusting clocks by an hour in spring and autumn after a survey found most Europeans opposed it.
Commission President Jean-Claude Juncker said millions “believe that in future, summer time should be year-round, and that’s what will happen”.
The Commission’s proposal requires support from the 28 national governments and MEPs to become law.
In the EU clocks switch between winter and summer under daylight saving time.
A European Parliament resolution says it is “crucial to maintain a unified EU time regime”.
However, the Commission has not yet drafted details of the proposed change.
In a consultation paper it said one option would be to let each member state decide whether to go for permanent summer or winter time. That would be “a sovereign decision of each member state”, Commission spokesman Alexander Winterstein explained on Friday.
He stressed that the proposal was “to no longer constrain member states into changing clocks twice per year”.
The UK is one of the 28 nations, but is due to leave the European Union in March 2019. Any change would be unlikely to happen before then.
