About Oslo's Time Zone
Oslo, the capital of Norway, uses Central European Time (CET, UTC+1) in winter and Central European Summer Time (CEST, UTC+2) in summer, following the same DST rules as the rest of the European Union. Clocks change on the last Sunday in March and October.
Oslo is always exactly 1 hour ahead of London, making it one of the easiest European cities to schedule meetings with from the UK. Oslo shares its time zone with Paris, Berlin, Amsterdam, Stockholm, and Copenhagen — providing excellent business connectivity across Western and Northern Europe.
The Oslo Stock Exchange (Oslo Børs) trades 9 AM to 4:30 PM CET/CEST. Norwegian business culture typically runs 8 AM to 4 PM, with an early start and early finish compared to many Southern European counterparts.
