Do East African countries observe Daylight Saving Time?

Which major countries use Eastern Africa Time (EAT)?
Eastern Africa Time is observed by Kenya, Ethiopia, Tanzania, Uganda, Madagascar, Somalia, and Djibouti. Among these, Kenya and Ethiopia are the zone's two largest economies, with Nairobi and Addis Ababa serving as the primary financial and administrative centers.
Is CST the same as Central Time (CT)?
Central Time (CT) is the umbrella term for the zone, while CST and CDT refer to its two seasonal offsets. CST (UTC-6) applies during standard time from November through March, and CDT (UTC-5) applies during Daylight Saving Time from March through November.
Does Mexico City use CST?
Mexico City operates on UTC-6, the same offset as CST, but it does not observe Daylight Saving Time following Mexico's elimination of the practice under a 2022 law. This means Mexico City stays at UTC-6 year-round while US and Canadian Central Time cities shift to UTC-5 each summer.
