7:00 pm PST to HST — 5:00 pm HST

7:00 pm Pacific Time (PST) is 5:00 pm Hawaii Time (HST) while both regions are on standard time. During the daylight saving period the answer becomes 4:00 pm, because one of the two zones shifts its clocks and the other does not.

Standard time

5:00 pm

Applies while neither zone is on daylight saving — broadly November to March in the northern hemisphere.

Daylight saving

4:00 pm

Applies while the clocks are forward. This pair does not keep a constant gap, so check the date.

How the two zones line up

Pacific Time runs at UTC−8 in winter and UTC−7 in summer. Hawaii Time runs at UTC−10 and UTC−10 respectively. Take the difference between the two, add it to 7:00 pm, and you get the local time on the other side.

Daylight saving

This pair is one of the awkward ones: the gap between the two zones is not constant, so a meeting booked in one season drifts by an hour in the other. Diary invitations sent as a fixed clock time rather than as a calendar event are the usual casualty.
