IST to EST quick reference

EST or EDT? Daylight saving explained

IST is India Standard Time, UTC+5:30, used across all of India. India does not use daylight saving, so IST never changes.

EST (UTC−5) is the winter name and EDT (UTC−4) the summer name. Most people write “EST” all year and mean whatever the clocks say in New York, so MeetETA reads EST as local Eastern time on the date you pick, and says so when that date is on EDT.

Right now India is on IST, UTC+5:30 and New York is on EDT, UTC−4 (the clocks at the top of the page always show the live values).

How the gap changes during the year

New York is 10.5 hours behind India while New York is on EST, and 9.5 hours behind India while New York is on EDT.
