About EAT

East Africa Time (EAT) is UTC+3. It is used in Kenya, Tanzania, Ethiopia, Uganda and Somalia.

East Africa Time is UTC+3 and fixed. Nairobi, Addis Ababa and Dar es Salaam all keep it. Ethiopia additionally uses a clock that counts from dawn rather than midnight for everyday purposes, six hours off the international one, so a time given locally in Addis may need converting twice rather than once.

About JST

Japan Standard Time (JST) is UTC+9. It is used in all of Japan, with no daylight saving.

Japan Standard Time is UTC+9 for the whole country and has had no daylight saving since 1951, when the occupation-era experiment was abandoned. Proposals to reintroduce it, most recently before the 2020 Olympics, have failed each time. The offset is shared with South Korea, so Tokyo and Seoul never differ by even a minute.

Does this gap change with the seasons?

Neither EAT nor JST shifts with the seasons, so this 6-hour difference holds all year. That is unusual enough to be worth relying on: most cross-continental gaps move twice a year.

This is the reason scheduling systems store an IANA zone such as Region/City rather than an offset or an abbreviation: the zone knows its own rules and the offset does not.
