What BST and EAT Actually Are
BST — British Summer Time
London, Manchester, Birmingham, Glasgow, and the rest of the UK from late March to late October. Standing at UTC+1:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to GMT. BST also stands for Bangladesh Standard Time (UTC+6). BDT is the clearer label for that one.
British Summer Time began in 1916 as a wartime fuel-saving measure and has run every year since, making it one of the oldest continuous daylight saving schemes in the world.
EAT — East Africa Time
Nairobi, Addis Ababa, Dar es Salaam, Kampala, Mogadishu. Standing at UTC+3:00 as written, and the region does not change its clocks, so that offset holds all year.
East Africa Time is shared by a run of countries down the Rift Valley, and Ethiopia additionally keeps a traditional 12-hour clock that starts counting at dawn.
What This Means in Practice
This gap is not fixed
BST changes its clocks and EAT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.
Close enough to share a working day
At only 2 hours apart, the two working days overlap almost completely. Scheduling is barely constrained by the difference.
