San Diego is 10 hours behind Istanbul

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

A 10-hour difference puts Istanbul and San Diego out of sync — when one team is mid-morning, the other is fast asleep. Consider rotating the inconvenience: one week Istanbul takes the early call, the next week San Diego does. Keep an eye on the calendar — San Diego observes daylight saving and Istanbul doesn't, which nudges this window by an hour twice a year.
