Why people convert Anchorage to Riyadh time
- Scheduling a call from Anchorage to Riyadh: a 10:00 AM start in Anchorage lands at 9:00 PM in Riyadh, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +11h gap: Anchorage and Riyadh have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Riyadh is 8:00 PM in Anchorage.
- Coordinating a Anchorage-based team with Riyadh contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM AKDT" is unambiguous; "3 PM" across a +11h gap is not.
- With a +11h gap there is no shared 9-to-5 window, so alternate the early start: one week Anchorage takes the early slot, the next week Riyadh does.
- Anchorage: Clocks fall back on Sun, Nov 1, 2026. Re-check this page after that date because the offset changes and so does the +11h gap.
About AKST (Alaska Standard Time)

About AST (Arabia Standard Time)
Arabia Standard Time (AST) is fixed at UTC+03:00 all year across Saudi Arabia, Qatar, Kuwait, Bahrain, Iraq and Yemen.

Arabia Standard Time is the same offset as Moscow Standard Time and East Africa Time, which makes scheduling with Europe straightforward — Riyadh is one hour ahead of Central European Time in winter and level with it during European summer time.
