When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Central Time and Dammam don't overlap on the same weekday. Dammam is 8 hours ahead of Central Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–12 PM in Central Time (3 PM–8 PM in Dammam) — suggest 9:00 AM Central Time (5:00 PM Dammam).
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.
