Time difference between Athens and Chicago
Chicago is 8 hours behind Athens
Athens, Greece is UTC+2 · Chicago, the United States is UTC−6 — 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 Athens goes forward on the last Sunday in March and back on the last Sunday in October and Chicago goes forward on the second Sunday in March and back on the first Sunday in November.
| Athens / Chicago clocks | Difference | How long |
|---|---|---|
| summer / summer, standard / standard | 8 hours behind | about 48 weeks — most of the year |
| standard / summer | 7 hours behind | about 4 weeks |
Both change their clocks and both are in the northern hemisphere, but not on the same weekend — Athens goes forward on the last Sunday in March and Chicago on the second 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 Athens and nine-to-five in Chicago 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.
