Eastern Time to India Time
Eastern Time is usually 9 hours 30 minutes behind India Standard Time while the U.S. is on daylight saving time, and 10 hours 30 minutes behind during Eastern Standard Time. India does not change clocks, so the whole difference comes from the Eastern side.
| Eastern U.S. | India | Difference |
|---|---|---|
| EST · UTC−5 | IST · UTC+5:30 | +10:30 |
| EDT · UTC−4 | IST · UTC+5:30 | +9:30 |
EST, EDT, and ET
10 AM EST is always 8:30 PM IST. 10 AM EDT is 7:30 PM IST. 10 AM Eastern Time depends on the date — winter uses EST, summer uses EDT. When the invite says Eastern Time rather than EST, choose ET to IST and set the meeting date.
ET to IST Converter
ET can mean EST or EDT depending on the date. India stays on IST year-round, so Eastern Time is either 9 hours 30 minutes or 10 hours 30 minutes behind India. Choose ET to IST at the top of this page and pick the date — you get New York's clock that day, converted to India Time.
EST vs EDT When Converting to India
EST is Eastern Standard Time, five hours behind UTC. EDT is Eastern Daylight Time, four hours behind UTC. India stays on IST, five and a half hours ahead of UTC, all year. EST to IST never changes: always 10 hours 30 minutes ahead, in January and in July. Current Eastern Time to India does change — 10 hours 30 minutes while New York is on EST, then 9 hours 30 minutes from mid-March to early November on EDT.
- EST = UTC−5 · IST = UTC+5:30 · IST is 10 hours 30 minutes ahead
- EDT = UTC−4 · IST = UTC+5:30 · IST is 9 hours 30 minutes ahead
- EST to IST stays the same all year
- ET to IST follows the date (EST or EDT)
If the invite names EST, stay on EST to IST. If it says Eastern Time or New York time, choose ET to IST and pick the date.

Eastern Time to India Meeting Planner
Morning in the East is evening in India. Each row shows two India times: daylight time first (mid-March to early November), then standard time. Highlighted rows are usually easiest on both sides.
| Eastern | India Time | For calls |
|---|---|---|
| 8:00 AM | 5:30 PM / 6:30 PM | Best overlap — early evening in India (5:30 / 6:30 PM IST) |
| 9:00 AM | 6:30 PM / 7:30 PM | Best overlap — evening in India (6:30 / 7:30 PM IST) |
| 10:00 AM | 7:30 PM / 8:30 PM | Still comfortable — mid-evening in India (7:30 / 8:30 PM IST) |
| 11:00 AM | 8:30 PM / 9:30 PM | Late evening for India (8:30 / 9:30 PM IST) |
| 12:00 PM | 9:30 PM / 10:30 PM | Too late for India (9:30 / 10:30 PM IST) |

EST to IST FAQ
- What is 10 AM EST in IST?
- 10 AM EST is 8:30 PM IST. Add 10 hours 30 minutes — Eastern mid-morning lands in India's prime evening.
- What is 11 AM EST in IST?
- 11 AM EST is 9:30 PM IST the same day. Add 10 hours 30 minutes to put late morning in the East into India's late evening.
- What is 12 AM EST in IST?
- 12 AM (midnight) EST is 10:30 AM IST the same day. Midnight in New York is mid-morning in India.
- Is India 9.5 or 10.5 hours ahead of Eastern Time?
- Both, depending on the season. India is 10 hours 30 minutes ahead of EST (the Eastern winter clock) and 9 hours 30 minutes ahead of EDT (the summer clock). India never changes its clocks — only the Eastern side moves. A converter that shows 9.5 hours while labeling EST is really converting from EDT.
- Does EST to IST change with daylight saving time?
- No. EST and IST keep the same clocks all year, so EST to IST is always 10 hours 30 minutes. What changes is current Eastern Time to India: while the U.S. is on EDT, India is 9 hours 30 minutes ahead instead.
- What is ET to IST?
- ET to IST converts current Eastern Time to India Standard Time — EDT in summer, EST in winter — while India stays on IST all year. That is 9 hours 30 minutes during daylight saving and 10 hours 30 minutes during standard time. Choose ET to IST at the top of this page and pick a date to see it.
- Which IST does this converter use?
- India Standard Time — the time across India, including Mumbai, Delhi, and Bangalore (five and a half hours ahead of UTC). IST can also mean Irish Standard Time or Israel Standard Time; this page only covers India.
