Open Meeting Planner →Chicago's finance and derivatives and logistics and Athens's shipping and tourism are different worlds, which is exactly why they call each other. The gap is 7 hours, with Athens the one whose clock reads later — and whose date has often already turned.
Both cities work Monday to Friday, Chicago typically 08:30–17:30 and Athens 09:00–17:00 local time. Watch for Thanksgiving (fourth Thursday of November, with the Friday) and Independence Day (4 July) in Chicago and Orthodox Easter (Good Friday to Easter Monday, April or May) and Independence Day (25 March) in Athens.
Only 1 office hour overlap — 09:00–10:00 in Chicago, 16:00–17:00 in Athens — so recurring meetings should hold that slot and everything else can go asynchronous. Each side observes daylight saving on its own schedule; the gap moves twice a year and back again.
Athens is 7 hours ahead of Chicago. The gap changes by an hour around the clock changes.
09:00–10:00 Chicago time, which is 16:00–17:00 in Athens — the 1-hour stretch when both are inside 09:00–17:00.
Both work Monday to Friday, so any weekday works — but check the date, since the day of the week can differ between the two cities at the same instant.
Not always. At 09:00 in Chicago it is already the next calendar day in Athens, so every invitation should carry the date in both cities.
