When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in China Standard Time and Cuba Standard Time don't overlap on the same weekday. Cuba Standard Time is 12 hours behind China Standard Time.
With some flexibility, there’s a workable window outside standard hours:
- 7 PM–8 PM in China Standard Time (7 AM–8 AM in Cuba Standard Time) — suggest 7:00 PM China Standard Time (7:00 AM Cuba 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.
