What CAT and ET Actually Are
CAT — Central Africa Time
Harare, Lusaka, Maputo, Khartoum. Standing at UTC+2:00 as written, and the region does not change its clocks, so that offset holds all year.
Central Africa Time has never used daylight saving. Near the equator the length of the day changes so little that there would be nothing to shift.
ET — Eastern Time
New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-5:00 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 EST.
Eastern Time covers roughly half the US population and, because of that, is the zone most American business defaults to when nobody specifies one.
What This Means in Practice
This gap is not fixed
ET changes its clocks and CAT 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.
