The short answer: India (IST, UTC+5:30) is 9.5 to 13.5 hours ahead of the US, depending on coast and season — East Coast is 9.5h in US summer (10.5h winter), Pacific is 12.5h summer (13.5h winter). The only comfortable overlap for a US-India team is US morning against India evening: roughly 8:00–10:00 AM ET equals 5:30–7:30 PM in India.
The United States and India sit almost exactly half a world apart, so there is no hour that is mid-afternoon in both places at once. For a distributed team this is the defining constraint: you get one usable window a day, and everything else is better handled async. The good news is that window is dependable, because India never changes its clocks.
How far ahead is India?
India keeps a single time zone, India Standard Time, at UTC+5:30, and it does not observe daylight saving. The US does, so the gap depends on the season and which US coast your team sits on.
| Your US zone | Ahead of you (US summer) | Ahead of you (US winter) |
|---|---|---|
| Eastern (ET) | 9.5 hours | 10.5 hours |
| Central (CT) | 10.5 hours | 11.5 hours |
| Mountain (MT) | 11.5 hours | 12.5 hours |
| Pacific (PT) | 12.5 hours | 13.5 hours |
The overlap window, worked out
Because India is ahead, your morning is their evening. The cleanest shared hours fall at the end of the Indian working day, which is early morning for you. Here is what common US morning times look like in India during US daylight saving.
| Your time | Eastern (ET) → IST | Pacific (PT) → IST |
|---|---|---|
| 8:00 AM | 5:30 PM | 8:30 PM |
| 9:00 AM | 6:30 PM | 9:30 PM |
| 10:00 AM | 7:30 PM | 10:30 PM |
| 12:00 PM | 9:30 PM | 12:30 AM (next day) |
| 5:00 PM | 2:30 AM (next day) | 5:30 AM (next day) |
For an East Coast team, 8:00–10:00 AM ET lands in the comfortable 5:30–7:30 PM IST evening band. The West Coast overlap is narrower and later for India: a 7:30 PM IST finish is only 7:00 AM PT, so the Pacific window is essentially the first hour of your workday. Anything past your late morning pushes India past 9 PM and out of sociable hours.
What to do with the rest of the day
Outside that single morning window there is no good live slot. For a US-India team that means leaning on async by default: written updates, recorded walkthroughs, and clear handoffs that let work pass between time zones overnight. Reserve live calls for the morning band, and if a meeting genuinely needs both sides awake more often, rotate the pain so neither coast always takes the early or late slot.
India never changes its clocks, but the US springs forward in March and falls back in November, so the gap moves by an hour. A standing US-India sync set in summer will land an hour off in winter unless you adjust it. See our guide on the best time to call India from the USA.
Find the overlap once, and keep it
Recomputing this offset by hand is exactly where the daylight-saving mistakes creep in. Atlas keeps India and your own city side by side in your Mac menu bar, shades the hours when both sides are awake, and writes any meeting to your calendar in both local times. It is also the fastest way to find your team's overlap window across more than two cities.
