EST is 10h30m behind IST. Subtract 10 hours 30 minutes from IST to get EST. The best India → US-East-Coast call windows are 6:30 – 9:00 PM IST (8:00 – 10:30 AM EST) or 8:00 – 10:00 AM IST the next day (9:30 – 11:30 PM EST the previous day). During US daylight saving the gap shrinks to 9h30m and the windows shift an hour.
EST is currently 9h30m behind IST.
Right now New Delhi / Mumbai (India) is on GMT+5:30 (UTC+5:30) and New York (US East Coast) on EDT (UTC-4). This flips back to the standard IST/EST gap once daylight saving ends.
Live clocks above use each region's current local time (DST-aware). The reference table below uses the fixed IST → EST standard offset — see the DST section for how the gap changes across the year.

Daylight saving and how the gap changes
IST stays at UTC+5:30 all year because India does not observe daylight saving. The US Eastern zone switches to EDT (UTC-4) from the second Sunday of March to the first Sunday of November. So the India ↔ US-East-Coast gap is 10h30m in US winter and 9h30m in US summer.
Common mistake: abbreviation collision
This page uses "IST" as India Standard Time (Asia/Kolkata, UTC+5:30). Irish Standard Time (UTC+1) and Israel Standard Time (UTC+2) share the abbreviation.
Frequently asked questions

- Does daylight saving affect the IST → EST gap?
- Yes. From mid-March to early November the US is on EDT (UTC-4), so the India ↔ US-East-Coast gap is 9h30m rather than 10h30m. India does not observe DST.
