Best time to call Dubai from Chicago (and vice versa)
With 9 hours between them there is no hour at which Chicago and Dubai are both inside a 9:00–17:00 working day. Teams split across these two cities usually alternate the sacrifice: one week the meeting lands early (7:00–8:00) in Chicago and late (18:00–19:00) in the other city, the next week the other way round. The Timezone Matcher grid shades exactly those compromise hours.

The two time zones

Chicago follows Central Time (CT): UTC−6 in winter (CST) and UTC−5 in summer (CDT), shared with Dallas, Houston and most of the US Midwest and South.
Dubai — Asia/Dubai
Dubai is on Gulf Standard Time, a fixed UTC+4 all year with no daylight saving — which is why its difference with Europe and the US shifts by an hour twice a year.
