Specific time, zone to zone

12:00 am GMT to IST — 5:30 am IST

12:00 am Greenwich Mean Time (GMT) is 5:30 am India Standard Time (IST) while both regions are on standard time. During the daylight saving period the answer becomes 4:30 am, because one of the two zones shifts its clocks and the other does not.

Standard time

5:30 am

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

Daylight saving

4:30 am

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

How the two zones line up

Greenwich Mean Time runs at UTC+0 in winter and UTC+1 in summer. India Standard Time runs at UTC+5:30 and UTC+5:30 respectively. Take the difference between the two, add it to 12:00 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.
