When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Colombia Time and Japan Standard Time don't overlap on the same weekday. Japan Standard Time is 14 hours ahead of Colombia Time.
With some flexibility, there’s a workable window outside standard hours:
- 5 PM–8 PM in Colombia Time (7 AM–10 AM the next day in Japan Standard Time) — suggest 6:00 PM Colombia Time (8:00 AM Japan Standard 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.
