Time difference between Melbourne and Chicago

Chicago is 15 hours behind Melbourne

Melbourne, Australia is UTC+10 · 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 Melbourne goes forward on the first Sunday in October and back on the first Sunday in April and Chicago goes forward on the second Sunday in March and back on the first Sunday in November.

These two are in opposite hemispheres, so their summers do not overlap: Melbourne is on summer time roughly when Chicago is not. The gap does not wobble by an hour around a settled figure — it swings between 15 hours and 17 hours and spends a good part of the year at each. There is no single right answer to give a calendar, which is why a recurring meeting between them is worth setting in one city's local time and letting the other side see it move.

When they can both be at their desks

Nine-to-five in Melbourne and nine-to-five in Chicago do not overlap at all. With 15 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.
