Dallas is 10.5 hours behind Kolkata

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

Don't expect an easy slot here: Kolkata and Dallas are 10.5 hours apart, with no overlap across conventional business hours. A shared overlap of zero doesn't mean zero collaboration; it just means leaning harder on documentation and clear ownership. Bear in mind Dallas shifts for daylight saving while Kolkata stays fixed — recheck these hours after each clock change.
