When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Dammam and Pacific Time don't overlap on the same weekday. Pacific Time is 10 hours behind Dammam.
With some flexibility, there’s a workable window outside standard hours:
- 5 PM–8 PM in Dammam (7 AM–10 AM in Pacific Time) — suggest 6:00 PM Dammam (8:00 AM Pacific 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.
