When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Korea Standard Time and Uruguay Time don't overlap on the same weekday. Uruguay Time is 12 hours behind Korea Standard Time.

With some flexibility, there’s a workable window outside standard hours:

  • 7 PM–8 PM in Korea Standard Time (7 AM–8 AM in Uruguay Time) — suggest 7:00 PM Korea Standard Time (7:00 AM Uruguay Time).

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.
