About CEST
Central European Summer Time (CEST) is UTC+2. It is used in Paris, Berlin, Madrid and Rome from late March to late October.
Central European Summer Time is UTC+2, in force from the last Sunday in March to the last Sunday in October. The European changeover happens at 01:00 UTC everywhere simultaneously, unlike the US which changes at 2am local time in each zone — so Europe's internal offsets never break during the transition, while North America's briefly do.
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.
Does this gap change with the seasons?
This gap is seasonal. The abbreviations themselves are fixed offsets, but the region on CEST switches to CET (UTC+1) from late October to late March. So the 1-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 CEST in EAT?
9:00 AM CEST is 10:00 AM EAT.
Is EAT ahead of CEST?
EAT is 1 hour ahead of CEST.
Which time zone does this use?
CEST is UTC+2 and EAT is UTC+3. 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.
