Greece to transition to winter time on October 25

Greece will transition to winter time on the morning of Sunday, October 25, marking the earliest clock change recorded since 2020. The shift occurs during the night between Saturday, October 24, and Sunday, October 25, when clocks will be set back one hour from 3:00 AM to 2:00 AM.

This seasonal adjustment follows European Union regulations designed to manage the transition between summer and winter time. While the practice was originally established to optimize natural light and reduce energy consumption—a measure that gained traction during the energy crisis of the 1970s—its modern utility has been debated. Recent discussions have focused on the potential impact of such changes on sleep patterns and biological rhythms, as well as the limited energy savings achieved in contemporary times.
