UTC to IST Converter
Convert Coordinated Universal Time (UTC) to India Standard Time (IST). Pick any date — daylight saving is applied from the IANA time zone database, so the answer is right in March and in November.
UTC to IST
UTC is 5 hours and 30 minutes behind IST.
Quick answer. IST is 5 hours and 30 minutes ahead of UTC, and that gap never changes. Neither UTC nor IST observes daylight saving time, so the same conversion is correct on every date of the year.
Time difference
Coordinated Universal Time (UTC)
UTC UTC+0:00 No DST
Used by aviation, servers, logs and international standards.
UTC never changes, and neither does IST, so this is the one conversion on the site with a single fixed answer all year: subtract 5 hours 30 minutes.
India Standard Time (IST)
IST UTC+5:30 No DST
Mumbai, Delhi, Bengaluru, Chennai, Kolkata, Hyderabad.
India runs on a single time zone, UTC+5:30, and has not observed daylight saving time since 1945. The half-hour offset is why IST conversions rarely land on a round hour.

Comparing a 9:00–18:00 working day in UTC against 9:00–17:00 in IST, across the whole week — a slot only counts if it lands on a working day at both ends.
Both sides work Monday to Friday, so the working weeks line up and you share 5 days.
Rows are days in UTC. Columns are hours of the UTC day.
