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