Frequently Asked Questions (GMT → GST)

How do I convert GMT to GST?

GMT (Greenwich Mean Time) uses the IANA timezone identifier Europe/London (standard offset +00:00), while GST (Gulf Standard Time) uses Asia/Dubai (standard offset +04:00). Use the interactive slider or the 24-hour table above to convert any hour accurately with automatic Daylight Saving Time (DST) adjustment.

What are the best meeting hours between London and Dubai?

Check the rows highlighted with "Best Meeting Overlap" in the 24-hour table above, where both GMT and GST fall within standard 9:00 AM – 5:00 PM working hours.

Does GMT to GST account for Daylight Saving Time (DST)?

Yes. Castov uses the browser's native IANA tzdb engine (Europe/London and Asia/Dubai), which automatically applies official Daylight Saving Time transitions.
