When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Cuba Standard Time and Bangladesh Standard Time don't overlap on the same weekday. Bangladesh Standard Time is 10 hours ahead of Cuba Standard Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 AM–10 AM in Cuba Standard Time (5 PM–8 PM in Bangladesh Standard Time) — suggest 8:00 AM Cuba Standard Time (6:00 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.
This window may shift by an hour during daylight saving time.
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.
