What is 1 AM IST in EST?

Does the answer change during the year?

Yes. India Standard Time and Eastern Time don't change their clocks on the same dates, so over the next 12 months:

• October 14 to October 31: 1 AM IST = 3:30 PM EST the previous day
• November 1 to March 13: 1 AM IST = 2:30 PM EST the previous day
• March 14 to October 13: 1 AM IST = 3:30 PM EST the previous day

Eastern Time switches between EST and EDT for daylight saving time; people often say EST all year.
