What time is GST when it is 12:00 CET?
15:00. Gulf Standard Time is 3 hours ahead of Central European Time in January and 2 hours ahead of it in July. The gap moves because Paris observes daylight saving and Dubai does not, so the difference between them is not a fixed number. A 9-to-5 day in Paris overlaps a 9-to-5 day in Dubai for 5 hours, between 09:00 and 14:00 CET.
Is the difference between CET and GST the same all year?
No, and this is the pair where that matters. Gulf Standard Time is 3 hours ahead of Central European Time in January and 2 hours ahead of it in July. The gap moves because Paris observes daylight saving and Dubai does not, so the difference between them is not a fixed number. Booking a recurring call across these two and assuming one number will drift by an hour twice a year — check the date, not just the zones.
What do CET and GST actually stand for?
CET is Central European Time, the zone covering Paris, currently UTC+1 in January. GST is Gulf Standard Time, covering Dubai, at UTC+4. One zone covers most of the continent — Paris, Berlin, Madrid, Rome, Warsaw and Stockholm all read the same clock, despite Madrid sitting almost as far west as London. Spain's clocks were moved to match Berlin in 1940 and never moved back.
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 Paris and Dubai?
A 9-to-5 day in Paris overlaps a 9-to-5 day in Dubai for 5 hours, between 09:00 and 14:00 CET. 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.

The difference, and whether you can rely on it
In January, Gulf Standard Time is 3 hours ahead of Central European Time — UTC+1 against UTC+4. In July it is 2 hours ahead instead. That is the part worth carrying away: this is not a pair you can memorise a single number for.
Why the gap moves
Paris observes daylight saving; Dubai does not. So the clocks in one city move twice a year while the other stays put, and the distance between them changes with them. Any calculation you did in one season is wrong in the other. The converter above uses the date you give it rather than today’s offset, which is the only way to get a future meeting right when it falls on the other side of a changeover.
When you can both be at a desk
A standard working day in Paris overlaps one in Dubai between 09:00 and 14:00 CET — 5 hours. Anything outside that asks somebody to start early or finish late.
Reading the abbreviations literally will mislead you
CET strictly means one fixed offset, but almost nobody uses it that way. People write it to mean the time in Paris, which shifts if that city observes daylight saving — and it does. 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.
One zone covers most of the continent — Paris, Berlin, Madrid, Rome, Warsaw and Stockholm all read the same clock, despite Madrid sitting almost as far west as London. Spain's clocks were moved to match Berlin in 1940 and never moved back. 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.
Scheduling something recurring
For a one-off, the converter above is the whole job. For a standing meeting across these two zones, where the gap changes, 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.
