EST vs undefined — which one do I use?
US Eastern Time switches between EST (UTC−5) and undefined (UTC±NaN). Daylight time (undefined) runs from the second Sunday in March to the first Sunday in November. India never changes, so the IST gap is 10 hours 30 minutes in winter and NaN hours in summer.

Frequently asked questions
What is the time difference between IST and EST?
IST is 10 hours 30 minutes ahead of EST (UTC−5). Because India does not observe daylight saving time, the gap changes by one hour when the US clocks change.
How do I convert IST to EST?
Subtract 10 hours 30 minutes to get EST from the IST time. Example: 9:00 PM IST is 10:30 AM EST. Use the converter above or the table below.
Is it EST or undefined right now?
US Eastern Time uses undefined (UTC±NaN) from the second Sunday in March to the first Sunday in November, and EST (UTC−5) the rest of the year. Most people say "EST" for whichever Eastern time is in force, so check which one applies on your date. The converter shows both answers.
Does India (IST) have daylight saving time?
No. India uses a single time zone, India Standard Time (UTC+5:30), all year, with no daylight saving. Only the other side of the conversion can change.
Does IST here mean India Standard Time?
Yes. IST is also used for Irish Standard Time and Israel Standard Time, but on this page IST always means India Standard Time (UTC+5:30).
