Frequently Asked Questions
What is the time difference between EAT and HST?
During standard time, Hawaii-Aleutian Standard Time is 13 hours behind Eastern Africa Time.
Do East African countries observe Daylight Saving Time?
None of the countries observing Eastern Africa Time use Daylight Saving Time. Situated close to the equator, these nations experience minimal seasonal variation in daylight hours, making clock changes unnecessary — EAT remains permanently fixed at UTC+03:00 throughout the year.
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.
Does Hawaii observe Daylight Saving Time?
Hawaii does not observe Daylight Saving Time and has not done so since 1947, remaining fixed at UTC-10:00 year-round. At roughly 20° North latitude, Hawaii's daylight hours vary by only about 1.5 hours between the summer and winter solstices — far too little to justify the disruption of a seasonal clock change.
Why is it called Hawaii-Aleutian time?
The name combines two geographically distant US territories that share the same UTC-10:00 standard offset: the Hawaiian Islands in the central Pacific and the westernmost Aleutian Islands of Alaska, which extend past the 180° meridian into the Eastern Hemisphere. Despite sharing a base offset, they behave differently — Hawaii observes no DST, while the Aleutian communities such as Adak do advance to HDT (UTC-9) each summer.
