Specific time, zone to zone

7:00 am PST to IST — 8:30 pm IST

7:00 am Pacific Time (PST) is 8:30 pm India Standard Time (IST) while both regions are on standard time. During the daylight saving period the answer becomes 7:30 pm, because one of the two zones shifts its clocks and the other does not.

Standard time

8:30 pm

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

Daylight saving

7:30 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. India Standard Time runs at UTC+5:30 and UTC+5:30 respectively. Take the difference between the two, add it to 7:00 am, 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.
