There is no time difference between Stockholm and Copenhagen. Both cities use Central European Time (CET/CEST, UTC+1/+2). When it's 12:00 PM in Stockholm, it's also 12:00 PM in Copenhagen.
Both cities observe daylight saving time on the same schedule as part of the European Union, so they remain synchronized year-round.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 6:00 PM) without any time conversion needed.
Stockholm and Copenhagen are the two largest Scandinavian capitals, separated by just the Øresund strait. The Øresund Bridge connects them, making travel between the cities possible in about 5 hours by car or train. Both are major Nordic business and tech hubs.
