Residents across Greece will need to adjust their timepieces as the country prepares for the seasonal shift to winter time. On the morning of October 25, 2026, at 4:00 a.m., all clocks will be set back to 3:00 a.m., effectively giving people an extra hour. This biannual practice remains part of the European Union's daylight saving time system, which aims to make better use of natural daylight during different seasons. The shift means sunrise and sunset times will occur earlier in the day as the winter months approach.
