IST to GMT

—

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

What is the IST to GMT time difference?

GMT is 5 hours 30 minutes behind IST. IST is India Standard Time at a fixed UTC+5:30, and GMT is Greenwich Mean Time at UTC+0. 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, subtract 5 hours 30 minutes from the IST time.

What time is 9 AM IST in GMT?

9 AM IST is 3:30 AM GMT. That follows from the gap of 5 hours 30 minutes between UTC+5:30 and UTC+0, so every IST hour moves by the same amount. The full 24-hour table above lists every hour, so you can convert any IST time to GMT at a glance. Because both are fixed offsets, that mapping is identical on any date — there is no daylight-saving exception to remember.

Is IST ahead of or behind GMT?

GMT is 5 hours 30 minutes behind IST, which is the same as saying IST is 5 hours 30 minutes ahead of GMT. That comes straight from the two offsets: UTC+5:30 for IST against UTC+0 for GMT. So at the same instant, 9:00 AM on IST reads 3:30 AM on GMT. Both are fixed named offsets, so the direction and the size of that gap hold all year.

Does IST to GMT change with daylight saving?

The IST↔GMT offset itself never changes: UTC+5:30 to UTC+0 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.
