What time is GST when it is 12:00 SGT?
08:00. Gulf Standard Time is 4 hours behind Singapore Time, all year round. A 9-to-5 day in Singapore overlaps a 9-to-5 day in Dubai for 4 hours, between 13:00 and 17:00 SGT.
Is the difference between SGT and GST the same all year?
Yes. Gulf Standard Time is 4 hours behind Singapore Time, all year round. Neither zone shifts in a way that changes the gap, so a time you work out once stays correct.
What do SGT and GST actually stand for?
SGT is Singapore Time, the zone covering Singapore, currently UTC+8 in January. GST is Gulf Standard Time, covering Dubai, at UTC+4. Singapore sits at UTC+8 despite being geographically closer to UTC+7, a legacy of aligning with Malaysia in 1982. No daylight saving, so it is one of the easier zones to schedule against.
Anything worth knowing about Gulf Standard Time?
Fixed at UTC+4 with no daylight saving. Worth remembering that the working week across much of the Gulf runs Monday to Friday now, but Friday is a half day in several countries and prayer times move the afternoon.
When is a good time to call between Singapore and Dubai?
A 9-to-5 day in Singapore overlaps a 9-to-5 day in Dubai for 4 hours, between 13:00 and 17:00 SGT. If the call has to happen outside that, the fairer arrangement is usually to alternate which side takes the awkward hour rather than always asking the same one.
How it works, and more about sgt → gst
The difference, and whether you can rely on it
In January, Gulf Standard Time is 4 hours behind Singapore Time — UTC+8 against UTC+4. It stays that way all year, so the number is worth memorising if you work across these two often.
When you can both be at a desk
A standard working day in Singapore overlaps one in Dubai between 13:00 and 17:00 SGT — 4 hours. Anything outside that asks somebody to start early or finish late.
Reading the abbreviations literally will mislead you
SGT strictly means one fixed offset, but almost nobody uses it that way. People write it to mean the time in Singapore, which shifts if the city observes daylight saving, which this one does not. This page follows the common usage rather than the strict one, because the strict reading gives an answer that is wrong for a good part of the year.

Scheduling something recurring
For a one-off, the converter above is the whole job. For a standing meeting across zones it is worth putting the invitation in a calendar that stores the zone rather than the time — then the changeover is handled for you and nobody has to remember. If you are trying to find a slot across more than two places at once, the meeting planner shows a whole day at a glance instead.
