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