San Diego is 12.5 hours behind Chennai

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

A 12.5-hour difference puts Chennai and San Diego out of sync — when one team is mid-morning, the other is fast asleep. Consider rotating the inconvenience: one week Chennai takes the early call, the next week San Diego does. Keep an eye on the calendar — San Diego observes daylight saving and Chennai doesn't, which nudges this window by an hour twice a year.
