Calculating time difference

Pick a date and time above.

EST = IST − 10 hours 30 minutes · IST = EST + 10 hours 30 minutes

IST and EST never change — India stays UTC+5:30 and EST stays UTC−5 all year, so this pair always converts with the same −10 hours 30 minutes. Use IST to ET when you want current Eastern Time for a specific date, including EDT during daylight saving.

IST to ET: India Time to Eastern Time

IST to ET depends on the date, because India uses IST year-round while U.S. Eastern Time switches between EST and EDT. That makes the gap −10 hours 30 minutes during Eastern standard time and −9 hours 30 minutes during daylight saving.

IST to Eastern Time

IST to Eastern Time means converting to whatever New York is on for the date you pick. In winter that is EST, and IST to EST is −10 hours 30 minutes. From mid-March to early November, New York runs on EDT, and IST to EDT is −9 hours 30 minutes.

Switch to IST → ET at the top of this page and pick the date — the converter shows India's clock next to New York's clock for that day.

What Is the Time Difference Between IST and EST?

EST is 10 hours 30 minutes behind IST, and IST is 10 hours 30 minutes ahead of EST. India Standard Time is UTC+5:30 and Eastern Standard Time is UTC−5, so subtract 10 hours 30 minutes when converting IST to EST. That gap never changes, because neither zone moves its clocks.

  • IST = UTC+5:30
  • EST = UTC−5
  • EST = IST − 10 hours 30 minutes
  • IST = EST + 10 hours 30 minutes

Example: 6 PM IST is 7:30 AM EST the same day. Midnight IST is 1:30 PM EST the previous day.

IST to EST vs IST to Eastern Time

EST and EDT are two different Eastern clocks — winter and summer. IST never changes. So the exact wording of a conversion matters: IST to EST is always the same subtraction, while IST to Eastern Time needs the date.

QueryMeaning
IST → ESTAlways −10 hours 30 minutes
IST → EDTAlways −9 hours 30 minutes
IST → ETDepends on the date — EST in winter, EDT in summer

If you are converting an actual meeting date in New York or another U.S. Eastern location, use IST → ET at the top of this page — New York is not on EST all year.
