GMT to IST

—

IST here means India Standard Time (UTC+5:30) — not Irish or Israel time.

What is the GMT to IST time difference?

IST is 5 hours 30 minutes ahead of GMT. GMT is Greenwich Mean Time at a fixed UTC+0, and IST is India Standard Time at UTC+5:30. Because both are named constant offsets rather than city clocks, the gap does not move — the 24-hour table above reads the same every day of the year. To convert by hand, add 5 hours 30 minutes to the GMT time.

What time is 9 AM GMT in IST?

9 AM GMT is 2:30 PM IST. That follows from the gap of 5 hours 30 minutes between UTC+0 and UTC+5:30, so every GMT hour moves by the same amount. The full 24-hour table above lists every hour, so you can convert any GMT time to IST at a glance. Because both are fixed offsets, that mapping is identical on any date — there is no daylight-saving exception to remember.

Is GMT ahead of or behind IST?

IST is 5 hours 30 minutes ahead of GMT, which is the same as saying GMT is 5 hours 30 minutes behind IST. That comes straight from the two offsets: UTC+0 for GMT against UTC+5:30 for IST. So at the same instant, 9:00 AM on GMT reads 2:30 PM on IST. Both are fixed named offsets, so the direction and the size of that gap hold all year.

Does GMT to IST change with daylight saving?

The GMT↔IST offset itself never changes: UTC+0 to UTC+5:30 is a constant 5 hours 30 minutes gap. Note: IST here means India Standard Time (UTC+5:30) — not Irish or Israel time. What can change is which abbreviation a region is using at a given date, which is why the notes above link across to the matching conversion. Converting between the named offsets themselves, as this page does, is the same arithmetic on every day of the year.
