Nairobi runs one hour ahead of Durban, every day of the year. When your Durban calendar shows 10:00, a colleague in Nairobi or a supplier in Mombasa sees 11:00. Durban stays on South Africa Standard Time (SAST, UTC+2). Nairobi stays on East Africa Time (EAT, UTC+3). Neither city observes daylight saving time, so the offset never shifts.
People often assume all of "Southern Africa" shares the same time. Kenya, Uganda, Tanzania and Ethiopia use EAT, one hour ahead of SAST. That means Durban is always behind Nairobi.

Nairobi is 1 hour ahead of Durban
Add one hour to Durban time to get Nairobi time. When Durban starts its work day at 08:00, Nairobi is already at 09:00. When Durban finishes at 17:00, Nairobi is at 18:00.
The relationship is fixed. Durban's offset to London shifts seasonally as the UK moves in and out of BST, but the Durban, Nairobi gap stays at one hour through every month of the year.
How much working time do Durban and Nairobi share?
Standard office hours in both cities run roughly 08:00 to 17:00. That gives a solid overlap window of seven hours.
Durban 09:00 to 16:00 equals Nairobi 10:00 to 17:00.
The only pinch point is the morning. If your Nairobi counterpart starts at 08:00 EAT, that is 07:00 in Durban. The reverse is easier: Durban's 08:00 start lands at 09:00 in Nairobi, a comfortable beginning for both sides.
Best meeting times for Durban, Nairobi calls
Book calls between 10:00 and 15:00 Durban time. That lands at 11:00 to 16:00 in Nairobi.
This window avoids lunch and end-of-day rushes on both sides. Durban lunch runs 13:00 to 14:00. Schedule at 12:00 Durban time (13:00 Nairobi) and you clear lunch entirely.
Skip early-morning slots. A 07:00 Durban call means your Nairobi contact is already at 08:00, but you are asking Durban participants to dial in before the standard work day begins.
The next practical change to note: South Africa has a public holiday on 1 January 2027 (New Year's Day). Kenya also observes New Year's Day. Check the South Africa Public Holidays 2026 page for the full list of days when Durban offices may be closed but Nairobi offices may be open. The one-hour gap itself will not change.
