EST is 10 hours 30 minutes behind IST in winter and 9 hours 30 minutes behind, as EDT, in summer. IST is India Standard Time, UTC+5:30 all year. EST is US Eastern Time, EST at UTC−5 in winter and EDT at UTC−4 in summer. 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 EST?
- EST is 10 hours 30 minutes behind IST in winter and 9 hours 30 minutes behind, as EDT, in summer. The table on this page lists common IST hours with their EST equivalents, and the converter gives the exact gap for any date you enter.
- What time is it in EST right now?
- The EST panel at the top of the page shows the current local time there, next to IST, so you can compare at a glance. The offset line under it reports the gap for this moment, so you do not have to work out which side of a clock change you are on.
- How do I convert a specific IST time to EST?
- Type the IST time into the box and the panel shows the same moment in EST. For example, 09:00 in IST on 1 June 2026 is 23:30 the day before in EST. A time with no zone is read as IST on this page; the selector under the box switches that to EST 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 EST difference change with daylight saving time?
- Yes, twice. EST moves its clocks on 8 March and 1 November in 2026, while IST stays at UTC+5:30 all year, so the gap changes by an hour on each of those dates. parsetime computes the offset for the exact instant you enter, so the days around a change come out right as well.
