San Diego is 12.5 hours behind Delhi

There is no standard 8-to-6 overlap. Someone joins early or late.

Set against a 12.5-hour difference, Delhi and San Diego run their workdays on completely separate schedules. Block a single recurring off-hours slot that both teams agree on, rather than negotiating a new awkward time every week. For part of the year the maths changes: San Diego observes daylight saving, Delhi does not, shifting the overlap by an hour.
