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

Popular EST to IST Conversions
Quick answers for the hours people look up most between the Eastern workday and India's evening — all on standard time.
11 AM EST to IST
11:00 AM EST is 9:30 PM IST. Add 10 hours 30 minutes — late morning in the East is late evening in India, the heart of the U.S.–India work overlap.
10 AM EST to IST
10:00 AM EST is 8:30 PM IST. Add 10 hours 30 minutes and the Eastern workday lands in India's prime evening hours.
9 AM EST to IST
9:00 AM EST is 7:30 PM IST the same day. An Eastern morning start is dinnertime in India — still just add 10 hours 30 minutes.
12 PM EST to IST
12:00 PM EST is 10:30 PM IST. Noon in the East is late evening in India — the last comfortable window for a same-day call.
8 AM EST to IST
8:00 AM EST is 6:30 PM IST. The start of the Eastern workday is early evening in India — a natural opening call for teams across both regions.
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 to India Time
EST is 10 hours 30 minutes behind India Standard Time. For example, 9 AM EST is 7:30 PM IST on the same day. When the U.S. is on daylight saving, Eastern clocks run on EDT and the gap narrows to 9 hours 30 minutes.
ET to IST Converter
ET can mean EST or EDT depending on the date. India stays on IST year-round, so ET to IST is normally either +9 hours 30 minutes or +10 hours 30 minutes. Switch to ET → IST at the top of this page and pick the date — the converter shows New York's clock for that day, converted to India Time.
What Is the Time Difference Between EST and IST?
IST is 10 hours 30 minutes ahead of EST, and EST is 10 hours 30 minutes behind IST. Eastern Standard Time is UTC−5 and India Standard Time is UTC+5:30, so add 10 hours 30 minutes when converting EST to IST. That gap never changes, because neither zone moves its clocks.
- EST = UTC−5
- IST = UTC+5:30
- IST = EST + 10 hours 30 minutes
- EST = IST − 10 hours 30 minutes
Example: 9 AM EST is 7:30 PM IST the same day. 2 PM EST is 12:30 AM IST the next day.
EST vs EDT When Converting to India
The 9.5-vs-10.5 confusion comes from EST and EDT being different clocks. EST is the Eastern winter clock, UTC−5. EDT is the Eastern summer clock, UTC−4. India stays on IST, UTC+5:30, all year.
EST to IST never changes: it is +10 hours 30 minutes in January and in July. What shifts is current Eastern Time to India — +10 hours 30 minutes while New York is on EST, then +9 hours 30 minutes from mid-March to early November when clocks move to EDT. If a source says IST is 9.5 hours ahead of EST, it is really describing EDT.
For invitations and deadlines that name EST explicitly, use EST → IST and add 10 hours 30 minutes. For “Eastern Time” or “New York time,” switch to ET → IST and pick the date.
Which IST Does This Converter Use?
On this page, IST means India Standard Time (UTC+5:30) — the time across India, including Mumbai, Delhi, and Bangalore.
IST can also mean Irish Standard Time or Israel Standard Time. Those are different zones; this page only covers India Standard Time.

Eastern Time to India Meeting Planner
Morning in the East is evening in India. The two IST values show the seasonal split: the first applies while the East is on EDT (mid-March to early November), the second during EST. Highlighted rows are the 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, so an Eastern mid-morning lands in India's prime evening.
- What is 9 AM EST in IST?
- 9 AM EST is 7:30 PM IST the same day. Morning standups on the East Coast are dinnertime calls in India.
- What is 12 AM EST in IST?

- How many hours ahead is IST from EST?
- 10 hours 30 minutes. EST is UTC−5 and IST is UTC+5:30, so IST = EST + 10 hours 30 minutes and EST = IST − 10 hours 30 minutes.
- 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.
- Why do some EST to IST converters show 9.5 hours and others 10.5 hours?
- Because they mix up EST with current Eastern Time. EST to IST is always 10 hours 30 minutes. But during daylight saving, New York runs on EDT, and EDT to IST is 9 hours 30 minutes. A converter that says 9.5 hours is really converting from EDT while labeling it EST.
- Does EST to IST change with daylight saving time?
- No. EST and IST never change — EST stays UTC−5 and India stays on IST 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, the gap narrows to +9 hours 30 minutes.
- 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 makes the gap +9 hours 30 minutes during daylight saving and +10 hours 30 minutes during standard time. Switch to ET → IST at the top of this page and pick a date to see it.
- What does IST mean on this converter?
- On this page, IST means India Standard Time (UTC+5:30) — the time across India. IST can also mean Irish Standard Time or Israel Standard Time, but this converter only covers India.
