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 GST
Gulf Standard Time (GST) is UTC+4. It is used in Dubai, Abu Dhabi and Muscat.
Gulf Standard Time is UTC+4, covering the United Arab Emirates and Oman, and there is no daylight saving anywhere on the Arabian peninsula. The scheduling complication in the region is not the clock but the week: the UAE moved its weekend to Saturday–Sunday in 2022, while Saudi Arabia and several neighbours keep Friday–Saturday, so a Thursday afternoon meeting lands differently across a border that has no time difference at all.
Does this gap change with the seasons?
Neither EAT nor GST shifts with the seasons, so this 1-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.
Frequently asked questions
What time is 9:00 AM EAT in GST?

Is GST ahead of EAT?
GST is 1 hour ahead of EAT.
Which time zone does this use?
EAT is UTC+3 and GST is UTC+4. Both abbreviations denote a single fixed offset, so this conversion never shifts with daylight saving — what changes is which abbreviation a place is using at the time.
