Best overlap: 8:00 AM to 9:00 AM in Kolkata is 5:30 PM to 6:30 PM in Anchorage.
Target 8:00 AM to 9:00 AM in Kolkata, which lands at 5:30 PM to 6:30 PM for the Anchorage side. With only around 1 hour of shared time, be precise — book 8:00 AM in Kolkata (5:30 PM in Anchorage) and you'll catch both teams. Remember Anchorage is a day apart — the previous day — so a late call for Kolkata could be the following morning there. Don't be caught out by clock changes — Anchorage observes daylight saving and Kolkata doesn't, so the offset varies by an hour through the year.
