In mainland Portugal and the Autonomous Region of Madeira, clocks will move forward one hour at 1 am on Sunday, 29 March, becoming 2 am.

In the Autonomous Region of the Azores, the change will take effect at midnight, moving to 1 am.

Legal time will change again on 25 October, to winter time.

The current time change regime is regulated by a 2000 directive (EU law), which stipulates that every year clocks are moved forward and backwards by one hour on the last Sunday of March and the last Sunday of October, respectively, marking the beginning and end of daylight saving time.

In September 2018, the European Commission proposed ending seasonal adjustment, but the process has been blocked since then due to disagreement among member states.

When questioned by the Lusa news agency, the European Commission said at the end of last week that "it is still possible" to reach a consensus to end the time change, adding that it will present a study on the matter later this year.

European Commission spokesperson Anna-Kaisa Itkonnen recalled that the executive decided to propose ending the time change in 2018 after receiving "requests from citizens and member states, a resolution from the European Parliament, several studies, as well as a public consultation" advocating this measure.
