Central European Time (Stockholm)

Sweden uses Central European Time, with Stockholm as its capital and largest city. Sweden adopted standard time in 1900 and is known for one of history's most chaotic timezone transitions — the 'Swedish calendar' of 1700-1712, when Sweden attempted to gradually shift from the Julian to Gregorian calendar by skipping leap days over 40 years, creating a calendar that matched no other country. Stockholm is a major European tech hub, producing companies like Spotify, Klarna, King (Candy Crush), and Skype. The city has more billion-dollar tech companies per capita than almost anywhere outside Silicon Valley. Sweden's extreme latitude means dramatic daylight variation — Stockholm gets about 18 hours of daylight at midsummer but only 6 hours in December. This drives the cultural importance of Midsommar (Midsummer) celebrations and contributes to the Swedish concept of 'mysa' (cozy) during dark winters. The Nasdaq Stockholm exchange operates on CET. Sweden's strong social welfare system, design tradition (IKEA, H&M), and innovation economy all function within the CET framework shared with its European neighbors.
