Seattle is 12.5 hours behind Hyderabad

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

Practically speaking, Hyderabad and Seattle never share office hours; 12.5 hours of separation keeps their days apart. To talk live, someone has to flex: an early start in Seattle can catch the tail end of the day in Hyderabad, or the other way round. One seasonal catch: Seattle springs forward and falls back, but Hyderabad doesn't, so the gap changes by an hour for several months of the year.
