What is BST in SAST?
South Africa Standard Time is 1 hour ahead
British Time is on UTC+1:00 and South Africa Standard Time is on UTC+2:00 right now. British Time is on daylight saving, so its clocks read BST. The gap changes during the year — see below.

When the difference changes
British Time and South Africa Standard Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – October 25, 2026South Africa Standard Time is 1 hour ahead
- October 25, 2026 – March 28, 2027South Africa Standard Time is 2 hours ahead
- March 28, 2027 – onwardsSouth Africa Standard Time is 1 hour ahead
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
British Time
Clocks go back one hour at 2am local time, becoming GMT.
South Africa Standard Time
South Africa Standard Time stays on SAST all year, so its offset from UTC never moves.

Scheduling between the two
Working hours overlap from 9:00 am to 5:00 pm BST, which is 10:00 am to 6:00 pm SAST. Anything inside that window falls in the normal working day at both ends.
A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.
British Time (BST) is used in the whole United Kingdom. In winter the UK is on GMT; from late March to late October it is on BST, an hour ahead.
