Best Time for a Call
There is no overlap between 9:00 AM and 5:00 PM office hours in these two zones. Stretching to early mornings and evenings, the workable window runs from 7:00 AM to 7:30 AM in PST, which is 8:30 PM to 9:00 PM in IST. One side ends up outside normal hours, so alternating who takes the awkward slot is a fair way to handle recurring calls.
