When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Colombia Time and China Standard Time don't overlap on the same weekday. China Standard Time is 13 hours ahead of Colombia Time.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Colombia Time (7 AM–9 AM the next day in China Standard Time) — suggest 7:00 PM Colombia Time (8:00 AM China 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.
