When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Mumbai and Callao don't overlap on the same weekday. Callao is 10 hours behind Mumbai.
With some flexibility, there’s a workable window outside standard hours:
- 6 PM–8 PM in Mumbai (7 AM–9 AM in Callao) — suggest 7:00 PM Mumbai (8:30 AM Callao).
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.
