UTC is 5 hours 30 minutes behind IST all year. IST is India Standard Time, UTC+5:30 all year. UTC is Coordinated Universal Time, the UTC+0 reference every other zone is measured from. Paste a Unix timestamp, an ISO 8601 string or a plain date such as June 1 2026 3:00 pm and the converter shows that moment in both zones, with UTC and Unix time alongside.

Common questions
- What is the time difference between IST and UTC?
- UTC is 5 hours 30 minutes behind IST all year. The table on this page lists common IST hours with their UTC equivalents, and the converter gives the exact gap for any date you enter.
- What time is it in UTC right now?
- The UTC panel at the top of the page shows the current local time there, next to IST, so you can compare at a glance. The gap is the same whatever the date, so the reading never needs adjusting.
- How do I convert a specific IST time to UTC?
- Type the IST time into the box and the panel shows the same moment in UTC. For example, 09:00 in IST on 1 June 2026 is 03:30 the same day in UTC. A time with no zone is read as IST on this page; the selector under the box switches that to UTC or to your own zone, and a Unix number or an ISO 8601 string with an offset is always read as written.
- Does the IST to UTC difference change with daylight saving time?
- No. Neither IST nor UTC observes daylight saving time, so the gap is 5 hours 30 minutes on every day of the year and there is no transition date to watch for.
