When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Colombia Time and Bangladesh Standard Time don't overlap on the same weekday. Bangladesh Standard Time is 11 hours ahead of Colombia Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–9 AM in Colombia Time (6 PM–8 PM in Bangladesh Standard Time) — suggest 8:00 AM Colombia Time (7:00 PM Bangladesh 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.
