Cairo is 13 hours ahead of Honolulu

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

Don't expect an easy slot here: Honolulu and Cairo are 13 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. One seasonal catch: Cairo springs forward and falls back, but Honolulu doesn't, so the gap changes by an hour for several months of the year.
