Switzerland operates on Central European Time (CET) during winter months, which is 1 hour ahead of Coordinated Universal Time (UTC+1). During daylight saving time, observed from the last Sunday in March to the last Sunday in October, Switzerland switches to Central European Summer Time (CEST), which is UTC+2.
All of Switzerland follows the same timezone. Major cities including Zurich, Geneva, Basel, Bern, and Lausanne all observe the same time. Despite having four official languages and 26 cantons, Switzerland maintains a single unified timezone.
Switzerland is world-famous for its precision watchmaking industry, centered in cities like Geneva and La Chaux-de-Fonds. Swiss watches have been synonymous with accuracy since the 16th century. The country is also home to CERN, where physicists study the fundamental nature of time and space.
