Chicago uses Central Time — Central Standard Time (CST, UTC−6) in winter and Central Daylight Time (CDT, UTC−5) in summer, shifting on the same US DST schedule. It sits one hour behind Eastern Time and two hours ahead of Pacific, placing it in the heart of US business scheduling overlap.
Dubai and the UAE use Gulf Standard Time (GST, UTC+4) year-round with no Daylight Saving Time. The fixed offset makes Dubai scheduling predictable throughout the year. As a major financial and logistics hub, GST is a widely used timezone in the Middle East and South Asia corridor.
Both Chicago and Dubai may observe Daylight Saving Time, which means the offset between them can change twice a year. Here is what to expect each season.
| Period | Note | Chicago | Dubai | Offset |
|---|---|---|---|---|
| Nov – Mar | Both on standard time | CST (UTC−6) | GMT+4 (UTC+4) | 10 hours |
| Mar – late Mar | US clocks forward, some zones still on standard | CDT (UTC−5) | GMT+4 (UTC+4) | 9 hours |
| Late Mar – Oct current | Both on summer / daylight time | CDT (UTC−5) | GMT+4 (UTC+4) | 9 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | CST (UTC−6) | GMT+4 (UTC+4) | 10 hours |
The transition window typically lasts 1–2 weeks in spring and autumn. If you have a recurring weekly meeting near a clock change, verify the exact date to avoid a missed call.
