Convert a specific time from GST to BST
Pick any time and date to convert it both ways. The conversion runs in your browser against the real zone rules, so a date inside a daylight saving period gets that period's offset rather than today's.
What is the time difference between GST and BST?
UK Time is 3 hours behind Gulf Standard Time. To go from GST to BST you subtract 3 hours. That gap is not fixed. Across 2026 the distance between these two zones takes 2 different values, from 3 hours to 4 hours, because UK moves its clocks and Gulf does not. This page recomputes it rather than assuming.

What are the best hours to schedule a call between GST and BST?
5 hours of the standard 9:00 am to 5:00 pm working day line up in both zones, from 12:00 pm GST to 5:00 pm GST. In UK that window reads 9:00 am to 2:00 pm. Outside it, one side is either not yet at their desk or already gone.
| GST | BST | Working hours | Note |
|---|---|---|---|
| 12:00 pm | 9:00 am | both sides | noon in Gulf, mid morning in UK |
| 1:00 pm | 10:00 am | both sides | afternoon in Gulf, mid morning in UK |
| 2:00 pm | 11:00 am | both sides | afternoon in Gulf, mid morning in UK |
| 3:00 pm | 12:00 pm | both sides | afternoon in Gulf, noon in UK |
| 4:00 pm | 1:00 pm | both sides | afternoon in Gulf, afternoon in UK |
Does daylight saving change GST to BST?
Gulf Standard Time does not move its clocks at all, so its UTC+4 offset holds every day of the year.
UK Time is currently on BST and changes next on Sunday, October 25, 2026, when the clock falls back from 1:59 am to 1:00 am and the offset moves from UTC+1 to UTC+0.
Because the two sides do not move together, the answer to this conversion changes during the year. For part of the year the gap is 3 hours and for the rest it is 4 hours. The table above is built for today, not for an average day.
Is GST ahead of or behind BST?
GST is ahead of BST by 3 hours: when it is 12:00 pm in Gulf, it is 9:00 am in UK. One wrinkle worth knowing: GMT and BST are two names for the same zone, not two zones. UK Time reads GMT in winter and BST in summer. When somebody types "gst to bst" they nearly always mean the zone rather than the literal winter offset, so this page resolves GST to Asia/Dubai and BST to Europe/London and applies whichever offset is genuinely in force on the day.
Gulf Standard Time covers Dubai, Abu Dhabi and Muscat. UK Time covers London, Cardiff, Edinburgh and Dublin. The identifiers behind them are Asia/Dubai and Europe/London, which is what any calendar or scheduling system should be storing rather than a fixed number of hours.
