Best overlap: 9:00 AM to 6:00 PM in Cape Town is 8:00 AM to 5:00 PM in London.
Your window to reach both cities is 9:00 AM to 6:00 PM in Cape Town, which converts to 8:00 AM to 5:00 PM in London. London is 1 hour behind Cape Town, yet you get a full 9 hours of shared hours — enough to schedule around lunches, focus time, and preferences with ease. Note the seasonal wrinkle: when London is on daylight saving and Cape Town isn't, the gap between them grows or shrinks by an hour.
