What GMT and WAT 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.
WAT — West Africa Time
Lagos, Abuja, Kinshasa, Luanda, Douala. Standing at UTC+1:00 as written, and the region does not change its clocks, so that offset holds all year.
West Africa Time covers a long north-south strip of the continent, and because it sits near the equator its daylight hours barely shift across the year.
What This Means in Practice
This gap is not fixed
GMT changes its clocks and WAT 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.
Same clock, two names
GMT and WAT currently show the same time, so no conversion is needed today. They are separate labels because the regions behind them do not always stay in step.
