When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Uruguay Time and Japan Standard Time don't overlap on the same weekday. Japan Standard Time is 12 hours ahead of Uruguay Time.
With some flexibility, there are two workable windows outside standard hours, depending on which side takes the early or late slot:
- 7 AM–8 AM in Uruguay Time (7 PM–8 PM in Japan Standard Time) — suggest 7:00 AM Uruguay Time (7:00 PM Japan Standard Time).
- 7 PM–8 PM in Uruguay Time (7 AM–8 AM the next day in Japan Standard Time) — suggest 7:00 PM Uruguay Time (7:00 AM Japan Standard Time).
Either is an early start or late finish for one side, but workable 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.
