About Central European Time (Paris)
Central European Time (CET) covers the majority of continental Western and Central Europe. France observes CET (UTC+1) in winter and CEST (UTC+2) in summer, with DST transitions on the last Sunday of March and October, synchronized across the European Union. Paris, the City of Light, is a global center for art, fashion, gastronomy, and diplomacy. Interestingly, France is geographically positioned to use GMT (like the UK and Portugal) but adopted CET during the German occupation in World War II and never reverted. This means France's clock time is actually about one hour ahead of its solar time, resulting in notably late sunsets in summer. The CET zone is the most populous timezone in Europe, covering over 400 million people. France's timezone affects its overseas territories differently — French Polynesia is UTC-10, Réunion is UTC+4, and New Caledonia is UTC+11. The European Parliament has debated ending seasonal clock changes, and while a 2019 vote favored abolishing DST, implementation has been delayed by disagreements among member states about whether to stay on permanent summer or winter time.
