Dubai Time Zone: GST, UTC+4, and Why the UAE Skipped Daylight Saving Time
Dubai runs on Gulf Standard Time (GST), UTC+4, year-round — no daylight saving time, ever. Learn what time it is in Dubai right now, how GST compares to EST, GMT, and IST, and why the UAE chose permanent standard time.
Dubai — and the UAE as a whole — operates on Gulf Standard Time (GST), which is UTC+4. That is 4 hours ahead of Coordinated Universal Time, and the offset never changes. The UAE does not observe daylight saving time. The clocks in Dubai stay at UTC+4 on every day of every year, making it one of the simpler time zones to work with once you know the offset.

Dubai Time vs Other Major Cities
Because Dubai does not observe DST, the offset to cities that do observe it shifts seasonally. The table below shows the offset during standard time (Northern Hemisphere winter) and during summer when those other zones switch to daylight saving.
| City | Offset from Dubai (winter) | Offset from Dubai (summer) |
|---|---|---|
| London (GMT/BST) | 4 hours behind Dubai | 3 hours behind Dubai |
| New York (EST/EDT) | 9 hours behind Dubai | 8 hours behind Dubai |
| Los Angeles (PST/PDT) | 12 hours behind Dubai | 11 hours behind Dubai |
| Mumbai (IST) | 30 minutes behind Dubai | 30 minutes behind Dubai |
| Singapore (SGT) | 4 hours ahead of Dubai | 4 hours ahead of Dubai |
| Tokyo (JST) | 5 hours ahead of Dubai | 5 hours ahead of Dubai |
| Sydney (AEST/AEDT) | 6–7 hours ahead of Dubai | 6 hours ahead of Dubai |
The Mumbai entry is a notable one: India Standard Time is UTC+5:30, which puts it just 30 minutes ahead of Dubai year-round. Given the very large Indian expat community in the UAE, this close relationship matters for both personal and business scheduling.
Why Dubai Does Not Observe Daylight Saving Time
The UAE has never observed daylight saving time. The practical reasons are straightforward: at Dubai's latitude (25° N), the difference between the shortest and longest days of the year is modest — about 4 hours — compared to 6 or more hours at the latitudes of Germany or the UK. The energy savings argument for DST, which was never particularly strong to begin with, is even weaker at lower latitudes.
Religious and cultural calendars tied to sunrise and sunset — particularly daily prayer times — also make a fixed UTC offset more practical. Seasonal clock changes would constantly shift prayer times relative to the work and school schedule.
Saudi Arabia, Qatar, Bahrain, Kuwait, and Oman also do not observe DST. The entire Arabian Peninsula runs on fixed UTC offsets year-round.
GST in Software: Using the IANA Identifier
If you are writing code that deals with Dubai or UAE time, use the IANA identifier "Asia/Dubai" rather than hardcoding UTC+4. While the UAE's rules have been stable for decades, using the IANA database means your code remains correct if rules ever change — and it is unambiguous. The abbreviation "GST" is not unique: it is also used for Georgia Standard Time (UTC+4) and was historically used for Gulf of Mexico zones.
- "Asia/Dubai" — correct IANA identifier for UAE time
- "Asia/Muscat" — Oman, same offset (UTC+4) as Dubai
- "Asia/Riyadh" — Saudi Arabia, UTC+3 (one hour behind Dubai)
- Never hardcode UTC+4 — use the IANA name so your code survives rule changes

Time in Dubai →Frequently asked questions
- What is the time difference between Dubai and the UK?
- Dubai is 4 hours ahead of the UK in winter (when the UK is on GMT) and 3 hours ahead in summer (when the UK switches to BST, British Summer Time). Dubai never changes its clocks, so the gap shifts depending on whether the UK is on DST.
- What is the time difference between Dubai and New York?
- Dubai is 9 hours ahead of New York in winter (when New York is on EST, UTC−5) and 8 hours ahead in summer (when New York is on EDT, UTC−4). Again, Dubai stays fixed at UTC+4 while New York changes.
- Does Dubai ever change its clocks?
- No. Dubai and the UAE as a whole do not observe daylight saving time. The clocks stay at UTC+4 (Gulf Standard Time) every day of the year.
