Johannesburg is 1 hour ahead of Copenhagen (winter) or the same time (summer). When it's 12:00 PM in Copenhagen, it's 1:00 PM in Johannesburg (winter). South Africa does not observe DST.
Copenhagen uses CET/CEST while Johannesburg uses SAST (South Africa Standard Time).
Optimal window: 9:00 AM - 5:00 PM Copenhagen time aligns well with Johannesburg business hours. The minimal time difference makes communication convenient.
Danish companies have significant investments in South Africa's green energy sector.
