Time zone difference between Santorini and Athens. UTC offsets and best meeting times.
Time difference: Santorini and Athens
Santorini and Athens share the same clock — both run on GMT+3 (UTC+3). There is no adjustment to make when scheduling calls, flights or messages between the two, and jet lag from the time change alone is not a factor on this route.
For calls, video meetings or messages between Santorini and Athens, aim for the overlap in normal waking hours on both sides rather than assuming a shared 9-to-5 — with a 0h gap, one side may need to join early morning or late evening. Business hours in Santorini typically start later than in Athens, so scheduling around late morning to early afternoon in the behind city usually finds the widest overlap.
Note that this 0h difference reflects current UTC offsets and can shift by an hour around daylight saving time (DST) clock changes if only one city observes it.
