Time difference between Chicago and Athens

Athens is 8 hours ahead of Chicago

Chicago, the United States is UTC−6 · Athens, Greece is UTC+2 — on standard time

The gap is not the same all year

Every converter gives one number for this pair. That number is right for most of the year and wrong for part of it, because Chicago goes forward on the second Sunday in March and back on the first Sunday in November and Athens goes forward on the last Sunday in March and back on the last Sunday in October.

Both change their clocks and both are in the northern hemisphere, but not on the same weekend — Chicago goes forward on the second Sunday in March and Athens on the last Sunday in March. For the days in between, the gap is neither party's expected figure, and a standing meeting silently moves by an hour. That mismatch is a common cause of a missed international call.

When they can both be at their desks

Nine-to-five in Chicago and nine-to-five in Athens do not overlap at all. With 8 hours between them, one side is always outside working hours, and the practical question is which side takes the early start or the late finish rather than when to meet.
