When to schedule

Standard business hours (9 AM–5 PM, Mon–Fri) in Cuba Standard Time and China Standard Time don't overlap on the same weekday. China Standard 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 China Standard Time) — suggest 7:00 AM Cuba Standard Time (7:00 PM China Standard Time).
  • 7 PM–8 PM in Cuba Standard Time (7 AM–8 AM the next day in China Standard Time) — suggest 7:00 PM Cuba Standard Time (7:00 AM China Standard 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
