About United Kingdom Time

The United Kingdom is on GMT (UTC+0) for about five months and BST (UTC+1) for the rest, changing on the last Sunday in March and the last Sunday in October. Ireland keeps exactly the same clock, so every figure here applies to Dublin as well as London.

Cities on this clock: London, Lisbon, Dublin, Edinburgh, Manchester.

About South Africa Standard Time

South Africa is a fixed UTC+2 and has never used daylight saving. Being in the southern hemisphere, its working day overlaps Europe most comfortably and North America least — and unlike its northern counterparts nothing about that changes through the year.

Cities on this clock: Johannesburg, Cape Town, Khartoum.

How the difference is worked out

The gap between United Kingdom Time and South Africa Standard Time is not one number. The two zones change their clocks on different dates, so for part of the year the difference is 1 hour and for the rest it is something else — the table above lists each stretch of 2026 with the date it starts and which country's clocks moved.

With both zones on their own standard time — daylight saving not in force anywhere — South Africa Standard Time is 2 hours ahead of United Kingdom Time. That figure never changes; everything else on this page follows from it plus whichever clocks have moved.

Every figure here comes from the IANA time zone database via your browser's own Intl engine, using the zone ids Europe/London and Africa/Johannesburg. Nothing is looked up on a server and nothing about your visit is recorded.
