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