There is no standard 8-to-6 overlap. Someone joins early or late.
Don't expect an easy slot here: Bengaluru and San Diego are 12.5 hours apart, with no overlap across conventional business hours. A shared overlap of zero doesn't mean zero collaboration; it just means leaning harder on documentation and clear ownership. One seasonal catch: San Diego springs forward and falls back, but Bengaluru doesn't, so the gap changes by an hour for several months of the year.
