India is 9 hours 30 minutes to 13 hours 30 minutes ahead of the United States, depending on which US time zone you're checking and whether the US is currently on daylight time. India itself never changes its clocks. It sits at a fixed UTC+5:30 all year, so the whole gap moves only because the US side does.

India vs Wenya's other major corridors
India runs 5 hours 30 minutes ahead of the UK in winter and 4 hours 30 minutes ahead during British Summer Time. It's 2 hours 30 minutes behind Singapore and, depending on the season, 4 to 5 hours behind Sydney. Of all these, the US-India gap is the widest, which is exactly why it causes the most scheduling mistakes — a small error on a five-hour gap costs you an early alarm, while the same error on a twelve-hour gap can mean missing the call entirely.
The mistake people make on this corridor
The half-hour offset is the trap. Someone in New York blocks out "10am IST" for a call, forgets the extra 30 minutes, and shows up either half an hour early or half an hour late depending on which way they rounded. The fix isn't memorising a number — it's checking the exact time before every call, because the US side of the gap also shifts twice a year while the India side never moves at all.
Does India observe daylight saving time?
No. India has used a single fixed time zone, IST at UTC+5:30, since 1947, and doesn't change its clocks for any part of the year. Every shift in the US-India gap comes entirely from the US side of the calculation, not from India's.
What is the time difference between USA and India right now?
With the US on daylight time, India is 9 hours 30 minutes ahead of the Eastern zone, 10 hours 30 minutes ahead of Central, 11 hours 30 minutes ahead of Mountain, and 12 hours 30 minutes ahead of Pacific. Once the US switches back to standard time in November, every one of those gaps grows by an hour.
What time should I schedule a call between the US and India?
Early morning on the US side lines up with early evening in India. A 7am to 9am Eastern call lands at 4:30pm to 6:30pm in Mumbai or Delhi, which is the most reliable overlap for a standard working day on both sides of one of the widest corridors Wenya's users deal with. West coast callers should push that window even earlier, since Pacific time trails Eastern by three hours on top of the existing gap.
