Best time for work calls
If you are scheduling a call between Johannesburg and London, the overlap window is limited to typical business hours. When it is 10 am in Johannesburg it is 9 am in London β a workable window for scheduling. The latest reasonable overlap is around 5 pm in Johannesburg (4 pm in London). Outside this window there is effectively no good overlap for regular office hours.
Best time for family calls
Johannesburg and London have a comfortable window for a family call β no awkward alarms required. Johannesburg is 1 hour ahead of London, which gives you 4 hours of genuine overlap when both sides are free. Aim for between 6 pm and 10 pm in Johannesburg β that lands at 5 pm to 9 pm in London, after the school run and before anyone's ready for bed. For a Sunday catch-up or a midweek check-in, this is the sweet spot.
