About converting GST to GMT

Gulf Time (Dubai) (Dubai) and Greenwich Mean Time (Greenwich) are in different time zones, so a meeting, call or stream that's convenient in one may be early or late in the other. The clocks above update live and account for daylight saving automatically, so the time difference you see is the real one for today — not a fixed number that goes stale twice a year.

To plan across the two, type a time into the GST box (or tap a quick preset) and read the GMT equivalent, including a "next day" or "previous day" note when the conversion crosses midnight. For any other pair of zones or cities, use the full timezone converter.

GST vs GMT: the time difference through the year

The difference stays the same all year: GMT is 4 h behind GST.

Daylight saving

Neither GST nor GMT uses daylight saving, so this conversion never changes.

Best time to meet

The two zones

GST · Gulf Time (Dubai)

Gulf Standard Time is UTC+4 all year, used in the UAE (Dubai, Abu Dhabi) and Oman. There is no daylight saving.

GMT · Greenwich Mean Time

Greenwich Mean Time is UTC+0 all year. It is the base for world time; the UK uses GMT only in winter and switches to BST in summer.

Frequently asked questions

6 answers
What is the time difference between GST and GMT?

How do I convert GST to GMT?
Enter a time in the GST box and the equivalent GMT time appears instantly, adjusted for the current offset between the two zones — including a note if it lands on the previous or next day.
Is this GST to GMT converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind Dubai and Greenwich), which tracks daylight-saving changes automatically, so the current times and difference are correct.
