When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Seoul and Reykjavík don't overlap on the same weekday. Reykjavík is 9 hours behind Seoul.
With some flexibility, there’s a workable window outside standard hours:
- 4 PM–8 PM in Seoul (7 AM–11 AM in Reykjavík) — suggest 6:00 PM Seoul (9:00 AM Reykjavík).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
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.
