9am in Johannesburg is 8am in London

When it’s 9am in Johannesburg, it’s 7am in London. London is 2 hours behind Johannesburg. London observes daylight saving time but Johannesburg does not, so the offset shifts by one hour when clocks change. The best time to schedule calls between the two cities is 11am to 6pm Johannesburg time (which is 9am to 4pm in London). Expats and travelers staying in touch between Johannesburg and London can usually find a comfortable calling window without anyone being up too early or too late. With a small gap, neither city bears a heavy scheduling burden, and both can usually accommodate calls without unusual flexibility. Setting a recurring family call at a fixed local time on both ends takes the guesswork out of staying connected across the distance.
