About converting SGT to GMT

Singapore Time (Singapore) and Greenwich Mean Time (Greenwich) 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 SGT box (or tap a quick preset) and read the GMT 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.

SGT vs GMT: the time difference through the year

The difference stays the same all year: GMT is 8 h behind SGT.

Daylight saving

Neither SGT nor GMT uses daylight saving, so this conversion never changes.

Frequently asked questions

6 answers
What is the time difference between SGT and GMT?
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 Singapore Time and Greenwich Mean Time, so the time you see is always right for right now.
How do I convert SGT to GMT?
Enter a time in the SGT box and the equivalent GMT 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 SGT to GMT converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Singapore and Greenwich), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in Greenwich right now?
The live clock above shows the current time in Greenwich (GMT), updating every second, alongside SGT.
Does the SGT to GMT time difference change?
No. Neither switch changes the gap: GMT is 8 h behind SGT all year.
What is a good meeting time for SGT and GMT?
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.
