Some Ethiopians use a 12-hour clock, with one cycle of 1 to 12 from dawn to dusk, and the other cycle from dusk to dawn. Unlike the convention in most countries, the start of the day is dawn, rather than midnight. Thus, 7:00 AM in East Africa Time corresponds to 1:00 in daylight hours in local Ethiopian time. 12:00 noon EAT is 6:00 in daylight hours, and 6:00 PM EAT is 12:00 in local time.
The current time convention persists despite inroads of international norms, partly driven by Ethiopia's pride in its never-colonized status.
