When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Kallakurichi and Eastern Time don't overlap on the same weekday. Eastern Time is 9 hours behind Kallakurichi.
With some flexibility, there’s a workable window outside standard hours:
- 5 PM–8 PM in Kallakurichi (7 AM–10 AM in Eastern Time) — suggest 6:00 PM Kallakurichi (8:30 AM Eastern Time).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
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.
