When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in San José and Shanghai don't overlap on the same weekday. Shanghai is 14 hours ahead of San José.
With some flexibility, there’s a workable window outside standard hours:
- 5 PM–8 PM in San José (7 AM–10 AM the next day in Shanghai) — suggest 6:00 PM San José (8:00 AM Shanghai).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
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.
