When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Pacific Time and Chennai don't overlap on the same weekday. Chennai is 13 hours ahead of Pacific Time.
With some flexibility, there are two workable windows outside standard hours, depending on which side takes the early or late slot:
- 7 AM–8 AM in Pacific Time (7 PM–8 PM in Chennai) — suggest 7:00 AM Pacific Time (7:30 PM Chennai).
- 7 PM–8 PM in Pacific Time (7 AM–8 AM the next day in Chennai) — suggest 7:00 PM Pacific Time (7:30 AM Chennai).
Either is an early start or late finish for one side, but workable 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.
