What MT and WAT Actually Are
MT — Mountain Time
Denver, Salt Lake City, Calgary, Edmonton — and Phoenix, which does not change its clocks. Standing at UTC-7:00 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, November 1, 2026, to MST.
Mountain Time contains the most conspicuous daylight saving exception in North America: Arizona, which has opted out since 1968.
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
MT 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, November 1, 2026 unless someone resets it.
