Why people convert Dubai to Chicago time

Scheduling a call from Dubai to Chicago: a 10:00 AM start in Dubai lands at 1:00 AM in Chicago, so you can confirm the slot without doing the arithmetic yourself.
Handling a -9h gap: Dubai and Chicago have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Chicago is 12:00 AM in Dubai.
Coordinating a Dubai-based team with Chicago contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM GST" is unambiguous; "3 PM" across a -9h gap is not.
With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week Dubai takes the early slot, the next week Chicago does.
Chicago: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.
