Winter time switch date confirmed

The switch to winter time in France will occur during the night of Saturday, October 24, to Sunday, October 25, 2026. At 3 a.m., the time will revert to 2 a.m., giving people an extra hour of sleep.

Historical context of the time change

This change, which aligns with the European Union's standardized schedule, takes place on the last Sunday of October each year. The practice was introduced in France following the 1973-1974 oil crisis to conserve energy.

Health and circadian effects

According to Dr. Gérald Kierzek, an emergency physician, the shift to winter time corresponds more closely to the natural UTC+1 time zone and aligns better with the light of the day, particularly in the morning. This can help regulate the circadian rhythm, which influences sleep, appetite, and mood.

Potential disruptions from the time change

However, the change can also cause disruptions, including sleep disturbances, reduced alertness, mood changes, or even physiological problems. The earlier onset of darkness associated with the time change may lead to lower mood and an increased risk of accidents in the evening.

Road safety concerns

Data from the National Interministerial Road Safety Observatory (ONISR) indicates a nearly 35% increase in pedestrian-related accidents during the week following the time change. In 2025, 48% of pedestrians killed were victims of nighttime incidents.

Safety recommendations

Road Safety officials are urging increased visibility for pedestrians, cyclists, and scooter users, as well as reduced speeds for drivers to enhance road safety.
