Converting IST to EST
Going the other way, India time is ahead, so you subtract: 9 hours 30 minutes while New York is on EDT and 10 hours 30 minutes while it is on EST. An Indian morning is the previous evening in the US.
India has no daylight saving, so IST is UTC+5:30 all year. Most people who search "EST" mean the local clock time on the US east coast. That clock is on EST (UTC-5) in winter and EDT (UTC-4) in summer; in 2026 EDT runs from March 8 until clocks go back on November 1. The converter above follows the real clock for the date you pick, so you do not have to remember which half of the year it is. The live line and the table use the same rules.
A 9:00 AM start in India is 11:30 PM the previous night on the east coast during EDT. For overlap, Indian evenings work: 7:30 PM IST is 10:00 AM Eastern during EDT.
IST here means India Standard Time. The abbreviation is also used for Irish Standard Time and Israel Standard Time, which is why writing "India time" avoids a wrong conversion.
