Dallas is 10.5 hours behind Hyderabad

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

Dallas is 10.5 hours behind Hyderabad, which is far enough that a normal 9-to-5 in one city never reaches the other's working hours. One practical option: Dallas dials in early while it's still late afternoon or evening in Hyderabad. Keep an eye on the calendar — Dallas observes daylight saving and Hyderabad doesn't, which nudges this window by an hour twice a year.
