In Slovenia, the standard time is Central European Time (Slovenian: Srednjeevropski čas; CET;).[1] Daylight saving time is observed from the last Sunday in March (02:00 CET) to the last Sunday in October (03:00 CEST).[2] This is shared with several other EU member states.
The Austro-Hungarian Empire adopted CET on 1 October 1891.[3] Slovenia would continue to observe CET after independence, and observed daylight saving time between 1941 and 1946, and again since 1983.[4]
Slovenia uses both the 12-hour and 24-hour clock.
