About EAT and GMT
EAT (East Africa Time) covers Kenya, Ethiopia, Tanzania, and Uganda and is anchored to the IANA zone Africa/Nairobi. It does not observe daylight saving time — the offset stays fixed all year.
GMT (Greenwich Mean Time) covers UK, Ireland, Iceland, and Portugal via Europe/London. It observes daylight saving time, so the gap between these two zones shifts twice a year.
Because at least one of these zones uses DST, the time difference between EAT and GMT is not constant — it shifts by an hour during the spring and autumn DST transitions. The hour grid below recomputes the difference for any specific date you click, using the IANA rules baked into your browser.
