About converting CST to SGT

Central Time (Chicago) and Singapore Time (Singapore) 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 SGT 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 SGT: the time difference through the year

The gap between CST and SGT 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 SGT?
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 Singapore Time, so the time you see is always right for right now.
How do I convert CST to SGT?
Enter a time in the CST box and the equivalent SGT 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 SGT converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Chicago and Singapore), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in Singapore right now?
The live clock above shows the current time in Singapore (SGT), updating every second, alongside CST.
Does the CST to SGT time difference change?
Yes. Over the next 12 months it is 13 h ahead or 14 h ahead, depending on the date — see the table of periods on this page.
What is a good meeting time for CST and SGT?
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.
