Best overlap: 10:30 AM to 6:30 PM in Kolkata is 8:00 AM to 4:00 PM in Tel Aviv.
Aim for 10:30 AM to 6:30 PM Kolkata time — that's 8:00 AM to 4:00 PM over in Tel Aviv. Despite the 2.5-hour difference, an 8-hour overlap keeps things simple and gives both teams breathing room. Finally, Tel Aviv observes daylight saving and Kolkata doesn't, so this window shifts by an hour for part of the year — recheck it each spring and autumn.
