About EST and IST
IST here is India Standard Time, Asia/Kolkata, UTC+5:30 all year. It is not Irish Standard Time and not Israel. Eastern Time is America/New_York.
Because India does not change clocks, the gap moves when New York does. EST to IST is 10 hours 30 minutes. EDT to IST is 9 hours 30 minutes. Half hours are normal on this page: 9:00 AM does not land on an hour in India.
| Zone | IANA | Standard | Daylight |
|---|---|---|---|
| Eastern Time | America/New_York | EST (UTC−5) | EDT (UTC−4) |
| India Standard Time | Asia/Kolkata | IST (UTC+5:30) | IST (UTC+5:30) |
Scheduling from New York to India
8:00 AM EST is 6:30 PM IST, after the Indian office day. 7:00 PM EST is 5:30 AM IST the next morning. The overlap is thin: a 7:00 AM New York call is 5:30 PM in India, late there and early in New York.
