What CET and GST Actually Are
CET — Central European Time
Paris, Berlin, Madrid, Rome, Amsterdam, Vienna, Warsaw, Stockholm. Standing at UTC+1:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to CET. Most of continental Europe moves to CEST (UTC+2) for the summer.
Central European Time spans a remarkable stretch of longitude — from Spain's Atlantic coast to Poland's eastern border — so solar noon in Madrid arrives nearly two hours later than in Warsaw.
GST — Gulf Standard Time
Dubai, Abu Dhabi, Sharjah, Muscat. Standing at UTC+4:00 as written, and the region does not change its clocks, so that offset holds all year. GST also refers to South Georgia Time (UTC-2), which you are very unlikely to want.
The Gulf states have never observed daylight saving, so Dubai's offset has been unchanged for decades — unusual stability for a region that grew as fast as it did.
What This Means in Practice
This gap is not fixed
CET changes its clocks and GST does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.
Close enough to share a working day
At only 2 hours apart, the two working days overlap almost completely. Scheduling is barely constrained by the difference.

Frequently Asked Questions
What is the time difference between CET and GST?
GST is 2 hours ahead of CET. That is the live figure. Taken strictly as written, the gap between CET and GST is 3 hours — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM CET in GST?
9:00 AM CET is 11:00 AM GST.
What are the best hours to schedule a call between CET and GST?
Between 9:00 AM and 3:00 PM CET, which is 11:00 AM to 5:00 PM GST. Both sides are inside normal business hours through that window.
Does the difference between CET and GST change during the year?
Yes. CET observes daylight saving and GST does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, October 25, 2026.
Does CET always mean Central European Time?
Most of continental Europe moves to CEST (UTC+2) for the summer.
Does GST always mean Gulf Standard Time?
GST also refers to South Georgia Time (UTC-2), which you are very unlikely to want.
