Central European Time (Oslo)

Norway uses Central European Time, stretching from its southern cities to well above the Arctic Circle. Oslo, the capital, is one of the world's most expensive cities and the center of Norway's petroleum-funded economy. Norway adopted standard time in 1895. The country's extreme latitude creates dramatic timezone experiences — Tromsø in the north experiences the midnight sun (24-hour daylight) from May to July and polar night (no sunrise) from November to January. Norway manages the world's largest sovereign wealth fund (the Government Pension Fund Global), valued at over $1.5 trillion, with investment decisions made on Oslo CET time. Stavanger is the oil capital of Norway, serving the North Sea petroleum industry. The Oslo Børs (Oslo Stock Exchange) operates on CET and is particularly important for energy, shipping, and seafood stocks. Norway is not an EU member but follows EU DST rules for practical coordination with its trading partners. The country's long coastline and maritime heritage mean Norwegian time has historically been crucial for shipping and fishing fleet coordination. The Svalbard archipelago, Norway's Arctic territory, also uses CET despite being at 78° North latitude.
