When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Cuba Standard Time and Hong Kong Time don't overlap on the same weekday. Hong Kong Time is 12 hours ahead of Cuba Standard Time.
With some flexibility, there are two workable windows outside standard hours, depending on which side takes the early or late slot:
- 7 AM–8 AM in Cuba Standard Time (7 PM–8 PM in Hong Kong Time) — suggest 7:00 AM Cuba Standard Time (7:00 PM Hong Kong Time).
- 7 PM–8 PM in Cuba Standard Time (7 AM–8 AM the next day in Hong Kong Time) — suggest 7:00 PM Cuba Standard Time (7:00 AM Hong Kong Time).
Either is an early start or late finish for one side, but workable 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.
