When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Mumbai and Porto Alegre don't overlap on the same weekday. Porto Alegre is 8 hours behind Mumbai.
With some flexibility, there’s a workable window outside standard hours:
- 4 PM–8 PM in Mumbai (7 AM–11 AM in Porto Alegre) — suggest 6:00 PM Mumbai (9:30 AM Porto Alegre).
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.
