Time difference between Chicago and Warsaw

Warsaw is 7 hours ahead of Chicago

Chicago, the United States is UTC−6 · Warsaw, Poland is UTC+1 — 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 Warsaw 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 Warsaw 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.
