When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Pacific Time and Arabia Standard Time don't overlap on the same weekday. Arabia Standard Time is 10 hours ahead of Pacific Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–10 AM in Pacific Time (5 PM–8 PM in Arabia Standard Time) — suggest 8:00 AM Pacific Time (6:00 PM Arabia Standard Time).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
Note: the working week in Saudi Arabia runs Sunday–Thursday; Friday–Saturday is the weekend, so overlap on those days is limited.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.
