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.
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.)
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.
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.
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.
EST is 10 hours 30 minutes behind IST, shifting by an hour around daylight-saving changes. 100% free, no registration, and fully private — every conversion happens in your browser.
Uses the IANA database for Asia/Kolkata and America/New_York, so daylight saving is applied automatically — no manual offset math.
Convert IST to EST the moment you pick a time. No signup, no ads in your way, nothing to install.
Spot the wide 10 hours 30 minutes gap between Mumbai and New York so you can plan async or off-hours calls.
Every conversion runs locally in your browser using your device clock. Your dates and times never touch a server.
