About IST to EST Converter

Convert India Standard Time to US Eastern time (New York, Washington, Boston, Miami) for any date. Eastern time is 10 hours 30 minutes behind India in winter (EST, UTC−5) and 9 hours 30 minutes behind during US daylight saving (EDT, UTC−4), from the second Sunday of March to the first Sunday of November. India does not change its clocks, so only the US side moves. The tool picks the right offset for the date you choose, marks a −1 day when New York is still on the previous date, and has a meeting planner for India–US calls.

How to Use

Set the India time

India is already in From and New York in To, at the time now in India. Change the Date and Time, or press Now to go back to the current time.

Read the New York time

The result shows the time in New York with EST or EDT and its UTC offset, a −1 day marker when the date is behind India's, and a line saying how far behind India it is.

Find a call slot

In Meeting planner, every hour of the chosen India day is lined up with New York. Set Working hours from and to; any hours that suit both appear under "Everyone is in working hours".

Swap for EST to IST

The swap button turns it round, so you can type a New York time, such as a webinar start, and see it in IST.

Rules & Limitations

US daylight saving runs from 2 am on the second Sunday of March to 2 am on the first Sunday of November (in 2027: 14 March to 7 November). India stays at UTC+5:30 all year.
With the default working hours of 9 am to 6 pm, India and New York do not share a full working hour. Widen the hours in the planner to see evening-in-India slots.
For about three weeks in March and one week around early November, the US has changed its clocks but the UK has not, so a US–UK gap is an hour shorter than usual if you add London to the planner.
The planner counts Monday to Friday in each city as working days and does not know public holidays in either country.

IST to EST Converter FAQ

How many hours is India ahead of New York?

India is 10 hours 30 minutes ahead of New York in winter (EST) and 9 hours 30 minutes ahead from mid-March to early November (EDT). The tool shows the exact difference for the date you pick.

Is it EST or EDT in New York right now?

New York uses EDT (UTC−4) from the second Sunday of March to the first Sunday of November and EST (UTC−5) the rest of the year. The result always shows which one applies, so you do not have to remember.

What is a good time for a call between India and the US East Coast?

Evening in India is morning in New York: 7 pm IST is 9:30 am EDT or 8:30 am EST. In the planner, set Working hours to end at 9 pm or 10 pm to see slots such as 7–10 pm IST in summer.

Why does New York show the previous day?

New York is behind India, so early in the Indian morning it is still the evening before there. The −1 day marker beside the result shows when the date is different.

How do I convert a US Eastern time to IST?

Press the swap button between the two places so New York is in From, then type the US time and date. The IST time appears in the result, with +1 day when it falls on the next date in India.
