When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Callao and Shanghai don't overlap on the same weekday. Shanghai is 13 hours ahead of Callao.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Callao (7 AM–9 AM the next day in Shanghai) — suggest 7:00 PM Callao (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.
