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