SAST to BST: SAST is 1 hour ahead of BST

Convert a specific time from SAST to BST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between SAST and BST?
UK Time is 1 hour behind South Africa Standard Time. To go from SAST to BST you subtract 1 hour. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 1 hour to 2 hours, because UK moves its clocks and South Africa does not. This page recomputes it rather than assuming.

Does daylight saving change SAST to BST?
South Africa Standard Time does not move its clocks at all, so its UTC+2 offset holds every day of the year.
UK Time is currently on BST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 1 hour and for the rest it is 2 hours. The table above is built for today, not for an average day.
Is SAST ahead of or behind BST?
SAST is ahead of BST by 1 hour: when it is 12:00 pm in South Africa, it is 11:00 am in UK. One wrinkle worth knowing: GMT and BST are two names for the same zone, not two zones. UK Time reads GMT in winter and BST in summer. When somebody types "sast to bst" they nearly always mean the zone rather than the literal winter offset, so this page resolves SAST to Africa/Johannesburg and BST to Europe/London and applies whichever offset is genuinely in force on the day.
South Africa Standard Time covers Johannesburg, Cape Town and Durban. UK Time covers London, Cardiff, Edinburgh and Dublin. The identifiers behind them are Africa/Johannesburg and Europe/London, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
