About Oslo's time zone

Oslo follows Central European Time (CET, UTC+1) in winter and CEST (UTC+2) during daylight saving from the last Sunday in March to the last Sunday in October. Norway's extreme northern latitude (Oslo is at 60°N) creates dramatic daylight variations — from about 17.5 hours of daylight in late June to just 6 hours in late December. The midnight sun phenomenon occurs north of the Arctic Circle, which lies entirely within Norway above Bodø.

Did you know? Norway is the world's largest per-capita producer of oil and gas outside the Middle East, and the Norwegian Oil Fund (Government Pension Fund Global) is the world's largest sovereign wealth fund, worth over $1.4 trillion. Oil trading — which happens in multiple time zones — has made Oslo's CET time zone a global reference for North Sea crude oil pricing.
