Frequently Asked Questions
What is the time difference between GMT and EAT?
During standard time, Eastern Africa Time is 3 hours ahead of Greenwich Mean Time.
What is the difference between GMT and BST?
GMT (Greenwich Mean Time) is the UK's standard winter offset at UTC+0, observed from the last Sunday in October through the last Sunday in March. BST (British Summer Time) is the daylight saving offset at UTC+1, applied each summer when clocks advance one hour.
Is GMT the same as UTC?
GMT and UTC share exactly the same numerical offset — both represent UTC+00:00 — but they are fundamentally different in nature. UTC is an atomic-clock-based international time standard used as the global reference, while GMT is a geographic time zone legally observed by specific countries including the United Kingdom and Ireland during winter months.
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.
