Does the difference change during the year?
No. India has no daylight saving time and UTC never changes, so the gap is always 5 hours 30 minutes.
Converting IST to UTC by hand
Take away 5 hours 30 minutes: 3:30 PM IST is 10:00 AM UTC.
Going back from UTC to IST, do the opposite: the UTC to IST page has its own table.
Reading a UTC timestamp as IST time
Logs, APIs and flight plans usually carry UTC. A timestamp ending in Z is UTC, and one ending in an offset already says how far from UTC it is. These two name the same moment:
2027-01-15T20:00:00Z2027-01-16T01:30:00+05:30
India has no daylight saving time, so this offset is the same on every date.
What IST and UTC mean
India Standard Time
IST here is India Standard Time, UTC+5:30, used in all of India all year: no daylight saving time and a single zone for the whole country.
IST can also mean Israel Standard Time (UTC+2, Israel) or Irish Standard Time (UTC+1, Ireland, in summer). This page uses India Standard Time, the meaning people searching for this conversion have in mind. For another one, type the city into the time zone converter.
Coordinated Universal Time
UTC is the world’s reference time. It has no daylight saving time and no seasons: every UTC offset you see (UTC−5, UTC+5:30) is measured from it.
