Time difference between Chicago and Brisbane

Brisbane is 15 hours ahead of Chicago

Chicago, the United States is UTC−6 · Brisbane, Australia is UTC+10 — 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 Brisbane does not change its clocks.
