Our free IST to EST converter instantly translates India Standard Time into US Eastern Time — the daily India-to-New-York conversion that distributed engineering and support teams depend on. It removes the awkward half-hour math and shows the exact local time in both Mumbai and New York, including the day rollover.

IST to EST Time Difference

India is far ahead of the US East Coast, and because India has no daylight saving, all the seasonal variation comes from the US side: (Offsets follow the IANA Time Zone Database.)

Standard time (IST vs EST): IST is 10 hours 30 minutes ahead of EST in winter. 5:30 PM IST is 7:00 AM EST.
US daylight time (EDT): when New York is on EDT (mid-March–early Nov), the gap shrinks to 9 hours 30 minutes. India never changes, so the shift is entirely on the Eastern side.
The 30-minute component (from IST's UTC+5:30 offset) is why IST–EST times rarely land on a round hour — a frequent scheduling slip the converter avoids.

Best Times to Schedule India ↔ New York Meetings

6:30–8:30 PM IST = 9:00–11:00 AM EST — India evening meets New York morning, the main overlap.
7:30–9:30 PM IST = 10:00 AM–12:00 PM EST — late India evening for a midday New York call.

Common Conversions

9:00 AM IST = 10:30 PM EST (previous day)
12:00 PM IST (noon) = 1:30 AM EST
5:30 PM IST = 7:00 AM EST
9:00 PM IST = 10:30 AM EST

Frequently Asked Questions

How many hours ahead is IST from EST?

IST is 10 hours 30 minutes ahead of EST during US standard time, and 9 hours 30 minutes ahead when New York is on EDT. So 5:30 PM IST is 7:00 AM EST in winter.

What is the best time for an India–New York call?

India evening (6:30–9:00 PM IST) lines up with New York morning (9:00–11:30 AM EST). That is the widest comfortable overlap given the 10.5-hour gap.

Why is IST to EST not a whole number of hours?

India Standard Time is UTC+5:30, a half-hour offset, so converting to EST (a whole-hour offset) always leaves a 30-minute remainder. The converter handles it precisely.
