When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Medellín and Riyadh don't overlap on the same weekday. Riyadh is 8 hours ahead of Medellín.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–12 PM in Medellín (3 PM–8 PM in Riyadh) — suggest 9:00 AM Medellín (5:00 PM Riyadh).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
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.
