About the two zones

Eastern Time (EST / EDT)

Eastern Time follows the clock in New York. It is Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) from the second Sunday in March to the first Sunday in November.

IANA zone
America/New_York
Offset
UTC−5 standard, UTC−4 daylight saving
Used in
the eastern United States and Canada
Major cities
New York, Toronto, Washington, D.C., Atlanta, Miami, Boston

People often write EST all year round. Strictly, EST is only the winter offset; in summer the eastern US is on EDT. The converter follows the real New York clock for the date you pick.

India Standard Time (IST)

India Standard Time is UTC+5:30 all year. The whole country keeps a single clock, and India has not observed daylight saving time since the 1940s, so IST never changes.

IANA zone
Asia/Kolkata
Offset
UTC+5:30 all year

IST can also stand for Irish Standard Time or Israel Standard Time. On this site IST always means India Standard Time (Asia/Kolkata).
