Converting EST to IST
India is ahead of the US east coast by 9 hours 30 minutes while New York is on EDT, and by 10 hours 30 minutes while it is on EST. The half hour comes from India Standard Time, UTC+5:30, which is why the answer rarely lands on a round hour.
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. India has no daylight saving, so IST is UTC+5:30 all year. 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.
For a working call, 8:00 AM to 10:00 AM Eastern during EDT is 5:30 PM to 7:30 PM in India. A US morning call is an Indian evening call, and a 9:00 AM Eastern start is 6:30 PM IST.
When the US clocks go back on November 1, 2026, the gap grows by an hour: 8:00 AM Eastern is 5:30 PM in India in October and 6:30 PM from November, so a recurring call shifts on the Indian clock even though nobody in India changed anything.
