Best time for work calls
If you are scheduling a call between Johannesburg and Houston, there is very limited or no overlap in normal business hours. Consider early-morning or late-evening calls for one side, or use async communication.
Best time for family calls
Johannesburg and Houston have a comfortable window for a family call β no awkward alarms required. Johannesburg is 7 hours ahead of Houston, 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 11 am to 3 pm in Houston, 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.
