Daylight saving time[edit]

Since 1981 the shifts to DST occur on the date as specified for the European Summer Time. Before DST was observed in 1941-1942.

Solar time[edit]

The difference of longitude between the western and easternmost points of Switzerland is equivalent to 4°32′09″, resulting in a difference of approximately 18 minutes of solar time.
