Best time to schedule a meeting
Standard 9–5 working hours do not overlap at all between EAT and EST. Someone has to take an early or late call — or use asynchronous communication instead.

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 EST
Eastern Standard Time (EST) is UTC−5. It is used in New York, Toronto, Miami and Atlanta in winter.
Eastern Standard Time is UTC−5 and applies in New York, Toronto, Miami and Atlanta only from November to March. For the other eight months those cities are on EDT, UTC−4. Americans routinely write "EST" year-round to mean "east coast time", so a date given as EST in July is usually meant as EDT and is an hour earlier than written — one of the most common scheduling errors there is. Note also that Panama and Jamaica are on UTC−5 all year and never switch.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on EST switches to EDT (UTC−4) from March to November. So the 8-hour figure on this page is correct for the part of the year when both places are actually on these abbreviations, and changes by an hour outside it.
EAT does not shift, so the whole change comes from one side. A recurring meeting fixed in EAT will appear to move by an hour for everyone on the other side, twice a year, without anyone changing anything.
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 EST?
9:00 AM EAT is 1:00 AM EST.
Is EST ahead of EAT?
EST is 8 hours behind EAT.
Which time zone does this use?
EAT is UTC+3 and EST is UTC−5. 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.
