What GMT and EAT Actually Are
GMT — Greenwich Mean Time
The UK and Ireland in winter, plus Iceland, Portugal and much of West Africa. Standing at UTC 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. Often used loosely as a synonym for UTC. They differ by less than a second, so for scheduling they are interchangeable.
Britain ran an experiment from 1968 to 1971 on permanent UTC+1, abandoning GMT entirely. It was scrapped after complaints about dark winter mornings in Scotland.
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
GMT 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.
