What changes in March and November

The United States moves its clocks forward one hour at 2:00 AM local time on the second Sunday of March and back one hour at 2:00 AM on the first Sunday of November. The US Department of Transportation is responsible for these rules and for the time zone boundaries.

India stays on UTC+5:30 throughout, so a recurring call booked in IST will move by an hour in New York twice a year, and one booked in New York time will move in India. The list below shows the exact dates for this year and next.

Working hours on both sides

There is no comfortable overlap between a 9-to-5 day in India and one in New York. The usual compromise is an early East Coast start: 8:30 AM EDT is 6:00 PM in India, and 8:30 AM EST is 7:00 PM. The alternative is a New York evening, which lands on the next morning in India.

Keep the date next to each time, since the calendar day often differs. The clocks for Washington, DC, Toronto and Delhi show the live times, and EST to IST runs the same sum the other way. For Chicago or Dallas, use IST to CST.

IST to EST questions

How many hours is IST ahead of EST?

IST is 10 hours 30 minutes ahead of Eastern Standard Time, used from early November to mid-March, and 9 hours 30 minutes ahead of Eastern Daylight Time for the rest of the year.

What is 8:00 PM IST in New York?

It is 9:30 AM in New York on EST and 10:30 AM on EDT, on the same date.

Is EST the same as ET?

ET, Eastern Time, is the zone name that covers both EST (UTC−5) and EDT (UTC−4). Saying ET avoids being wrong about the season.

Do India and the US change clocks on the same day?

India never changes its clocks. Only the US side moves, on the second Sunday of March and the first Sunday of November.

Does Toronto use the same time as New York?

Yes. Ontario and Quebec follow Eastern Time with the same daylight saving dates as the US East Coast.
