London and Johannesburg: time difference and best meeting times

Computed from the platform's time zone data for 2026. Last updated 6 October 2026.

Johannesburg is 1 hour ahead of London for most of 2026. With a 9:00 to 17:00 working day in both places, you share up to 7 hours each day, which is enough for a full block of meetings.

Shared working hours

The table assumes a working day of 9:00 to 17:00 in both cities. Times are local to each city. January and July show the two ends of the year, because daylight saving changes the picture.

Season	Time difference	Shared hours	Shared window in London	Shared window in Johannesburg
January (15 January)	2 hours	6 hours	09:00 to 15:00	11:00 to 17:00
July (15 July)	1 hour	7 hours	09:00 to 16:00	10:00 to 17:00

Put recurring meetings inside the shared window, and use the rest of the day for focused work. A good default slot is 12:00 to 13:00 in London, which is 13:00 to 14:00 in Johannesburg. With this much overlap you can alternate which side sits closer to the edge of their day, so one team is not always the one meeting early.

With a longer day, 08:00 to 18:00

If people on both sides can start an hour earlier and finish an hour later, the shared time becomes 8 hours in January and 9 hours in July. In January that is 08:00 to 16:00 in London, which is 10:00 to 18:00 in Johannesburg. In July it is 08:00 to 17:00 in London, which is 09:00 to 18:00 in Johannesburg.

29 March to 24 October	Johannesburg is 1 hour ahead of London

A meeting that sits comfortably in the shared window for part of the year can land outside it for a few weeks. Check the table above whenever you set a recurring meeting that spans a change.

Tips for teams in London and Johannesburg

Name both cities in the invitation, for example "12:00 to 13:00 London / 13:00 to 14:00 Johannesburg".
Check recurring meetings when clocks change. The gap is 2 hours instead of 1 hour for part of the year, so the shared window moves.
Keep the shared 6 hours for meetings, and do focused work outside it.
