Greece to transition to winter time on October 25, 2026

The transition to winter time is scheduled for the last Sunday of October. In 2026, clocks will be set back one hour on Sunday, October 25, at 03:00, marking the earliest such change since 2020.

The practice of adjusting clocks aims to maximize daylight usage and conserve energy. While the concept of daylight saving time has historical roots involving figures like Benjamin Franklin and William Gillette, the modern scientific approach is attributed to New Zealand entomologist George Hudson. This time adjustment practice has been applied pan-Europeanly since 1996, while Greece first implemented it in 1975.
