Frequently Asked Questions (GST → GMT)

How do I convert GST to GMT?

GST (Gulf Standard Time) uses the IANA timezone identifier Asia/Dubai (standard offset +04:00), while GMT (Greenwich Mean Time) uses Europe/London (standard offset +00:00). 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 Dubai and London?

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