USA to India Time Converter
In winter, India (IST) is 10 hours 30 minutes ahead of the US East Coast (EST), 11h 30m ahead of Central, 12h 30m ahead of Mountain, and 13h 30m ahead of Pacific Time. During US daylight saving time each gap is 1 hour shorter, except in most of Arizona, which stays 12h 30m behind India.
A 9:00 AM Start in Each US Zone, in India
The US has no single time, so the same 9:00 AM office start reaches India at a different hour from each zone:
| US zone | 9:00 AM there is, in India |
|---|---|
| Eastern (New York, Atlanta) | 7:30 PM on standard time, 6:30 PM on daylight time |
| Central (Chicago, Dallas) | 8:30 PM on standard time, 7:30 PM on daylight time |
| Mountain (Denver, Salt Lake City) | 9:30 PM on standard time, 8:30 PM on daylight time |
| Arizona (no clock change) | 9:30 PM all year |
| Pacific (Los Angeles, Seattle) | 10:30 PM on standard time, 9:30 PM on daylight time |
| Alaska (Anchorage) | 11:30 PM on standard time, 10:30 PM on daylight time |
| Hawaii (no clock change) | 12:30 AM the next day all year |
India never changes its clocks, so every shift in this table comes from the US side.

An India 9:00 AM Start in Each US Zone
Going the other way, the India morning is the evening before in every US zone:
| US zone | India's 9:00 AM is, there |
|---|---|
| Eastern (New York, Atlanta) | 10:30 PM the previous day on standard time, 11:30 PM the previous day on daylight time |
| Central (Chicago, Dallas) | 9:30 PM the previous day on standard time, 10:30 PM the previous day on daylight time |
| Mountain (Denver, Salt Lake City) | 8:30 PM the previous day on standard time, 9:30 PM the previous day on daylight time |
| Arizona (no clock change) | 8:30 PM the previous day all year |
| Pacific (Los Angeles, Seattle) | 7:30 PM the previous day on standard time, 8:30 PM the previous day on daylight time |
| Alaska (Anchorage) | 6:30 PM the previous day on standard time, 7:30 PM the previous day on daylight time |
| Hawaii (no clock change) | 5:30 PM the previous day all year |
India's 6:00 PM finish is 7:30 AM on the East Coast in winter and 8:30 AM in summer.
Why a US Time Reaches India an Hour Earlier in Summer
When the US moves to daylight time on the second Sunday in March, a fixed US clock time is one hour closer to India. An Eastern 9:00 AM was 7:30 PM in India the week before and is 6:30 PM the week after. It goes back on the first Sunday in November. Arizona and Hawaii do not move, so for them the numbers in the table above never change.
Most people only need one row of the first table. If you are not sure which US zone a colleague means by "ET", "CT" or "PT", ask for the city: Phoenix and Los Angeles look the same in July and are an hour apart in January.
An Eastern Morning Call and an India Evening
If you're on the US East Coast, a 9:00 AM start is 7:30 PM in India in winter and 6:30 PM in summer, so the call lands in the India evening either way. Pushing it to 10:00 AM gives 8:30 PM on EST and 7:30 PM on EDT, which is late for the India side.
India's 6:00 PM is 7:30 AM in the US in winter and 8:30 AM in summer, which is the latest start time to use if an India colleague has to finish by then. For a team on the West Coast, the same India 6:00 PM is only 4:30 AM in winter, so those calls are better held in the Pacific evening.
Put both time zones in the invite and check the date for any meeting near the second Sunday in March or the first Sunday in November.
