What CST and EAT Actually Are
CST — Central Standard Time
Chicago, Houston, Dallas, Mexico City, Winnipeg. Standing at UTC-6:00 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 CST. CST also stands for China Standard Time (UTC+8) and Cuba Standard Time (UTC-5). This page covers the North American one.
Saskatchewan sits inside the Central zone but never changes its clocks, so it matches CST in winter and its neighbors' MDT in summer.
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
The date changes mid-working-day
For 1 of the eight hours in a normal CST working day, the equivalent EAT time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.
This gap is not fixed
CST 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, November 1, 2026 unless someone resets it.
