What EST and EAT Actually Are
EST — Eastern Standard Time
New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-5:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to EST. Australia also uses EST for its own Eastern Standard Time (UTC+10), now more often written AEST.
Eastern Standard Time is only actually in force from early November to mid-March. For the other eight months the same region is on EDT, which is why so many EST conversions are quietly wrong.
EAT — East Africa Time
Nairobi, Addis Ababa, Dar es Salaam, Kampala, Mogadishu. Standing at UTC+3:00 as written, and the region does not change its clocks, so that offset holds all year.
East Africa Time is shared by a run of countries down the Rift Valley, and Ethiopia additionally keeps a traditional 12-hour clock that starts counting at dawn.
What This Means in Practice
This gap is not fixed
EST changes its clocks and EAT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.
