UTC offset
UTC+03:00
Riyadh does not observe daylight saving time. Clocks stay on UTC+03:00 all year long.
Arabian Standard Time (AST)
Arabian Standard Time (AST, UTC+03:00) is the everyday clock across six Gulf and Arabian Peninsula countries—Yemen, Iraq, Bahrain, Kuwait, Qatar, and Saudi Arabia—with no daylight saving changes to track. That makes AST one of the most steady timekeeping anchors in the region, whether you’re scheduling a call to Riyadh, Doha, Aden, or Kuwait City.
Six countries follow Arabia Standard Time without daylight saving: Yemen, Iraq, Bahrain, Kuwait, Qatar, and Saudi Arabia.
No. AST never moves for daylight saving. The offset stays the same all year, which can simplify cross-Gulf schedules.
They sit near similar longitudes and benefit from consistent clocks across borders for trade, logistics, media schedules, and telecommunication.
AST and Gulf Standard Time often refer to the same UTC+03:00 belt. Some labels use “Gulf Standard Time” as a more marketing-friendly term, but in practice they map to the same Arabia Standard Time regions.
AST is usually two hours ahead of London (outside of British Summer Time) and one hour ahead of Central European Time. That makes late morning in Europe and early afternoon in many AST cities align well, while late afternoon in AST rolls over into middle of the day in the US.
There are six IANA zones grouped under AST today: Asia/Aden, Asia/Baghdad, Asia/Bahrain, Asia/Kuwait, Asia/Qatar, and Asia/Riyadh.
Riyadh and Doha both use AST (UTC+03:00). Dubai is in the UAE, there the official IANA zone is Asia/Dubai, also at UTC+03:00 but a 'different' named zone. (The time is synchronous but the label differs.)
Treat AST as a fixed UTC+03:00 anchor. That means you can set your world clock or meeting tool once without worrying about midyear shifts, making sprint planning, support rotations, and broadcast times easier to coordinate with Gulf partners.
