What is Heure Hiver?

Heure Hiver, translated as "winter time," is a period in France when clocks are set back one hour to gain an extra hour of daylight in the evening. This time change was initially introduced during World War I to conserve energy and has continued as an annual practice.

When Does Heure Hiver Begin and End?

Heure Hiver typically begins on the last Sunday of October and ends on the last Sunday of March. In 2023, Heure Hiver will begin on October 29th and end on March 26th, 2024.

Why is Heure Hiver Implemented?

1. Energy Conservation: The primary reason for Heure Hiver is energy conservation. By shifting the daylight hours, individuals can take advantage of natural light in the evening, reducing the need for artificial lighting. 2. Improved Safety: Heure Hiver provides an extra hour of daylight in the evening, enhancing visibility and reducing accidents associated with low-light conditions. 3. Health and Well-being: Exposure to sunlight during waking hours has been linked to improved mood, sleep quality, and overall well-being. Heure Hiver allows for more time outdoors and natural light exposure.
