About converting CST to GST

Central Time (Chicago) and Gulf Time (Dubai) (Dubai) are in different time zones, so a meeting, call or stream that's convenient in one may be early or late in the other. The clocks above update live and account for daylight saving automatically, so the time difference you see is the real one for today — not a fixed number that goes stale twice a year.

To plan across the two, type a time into the CST box (or tap a quick preset) and read the GST equivalent, including a "next day" or "previous day" note when the conversion crosses midnight. For any other pair of zones or cities, use the full timezone converter.

CST vs GST: the time difference through the year

The gap between CST and GST changes during the year because only one of them uses daylight saving.

Frequently asked questions

6 answers
What is the time difference between CST and GST?
It's shown live at the top of this page (and it can change with daylight saving). The converter uses the current, DST-aware difference between Central Time and Gulf Time (Dubai), so the time you see is always right for right now.
How do I convert CST to GST?
Enter a time in the CST box and the equivalent GST time appears instantly, adjusted for the current offset between the two zones — including a note if it lands on the previous or next day.
Is this CST to GST converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Chicago and Dubai), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in Dubai right now?
The live clock above shows the current time in Dubai (GST), updating every second, alongside CST.
Does the CST to GST time difference change?
Yes. Over the next 12 months it is 9 h ahead or 10 h ahead, depending on the date — see the table of periods on this page.
What is a good meeting time for CST and GST?
Standard 9-to-5 office hours don't overlap; early morning in one zone and evening in the other is the usual compromise — see the table on this page.
