EST to IST converter
When your day starts in New York, India’s workday is ending. The gap is 10½ hours from November to March and 9½ hours the rest of the year.
India is 10 hours 30 minutes ahead of New York from November to March, and 9 hours 30 minutes ahead the rest of the year.
Living on Eastern Time with a foot in India
Most people who look up this conversion are in the US and need something from India: an answer from a colleague, a call with parents, a cricket score. Because India is so far ahead, the useful hours are squeezed into the edges of the American day.
Managing a team or vendor in India
Your morning is their evening, so the first two or three hours of the Eastern workday are the only live overlap.
- Book stand-ups and reviews between 8 and 10:30 AM ET. After that your Indian colleagues are past 8 PM.
- Work handed over by end of day IST is ready at 7:30 AM EST / 8:30 AM EDT, so review it first thing.
- By 7 AM on Monday in New York, your India team has already worked most of their Monday.
- Anything sent after 12:30 PM ET on a Friday reaches India on Friday night or later, so expect the reply on Monday.
Calling parents and family in India
Two windows work every day, one at each end of your day.
- Your morning, 7–9 AM ET = their evening, 5:30–7:30 PM IST in winter or 4:30–6:30 PM IST in summer
- Your night, 8–10 PM ET = their next morning, 6:30–8:30 AM IST in winter or 5:30–7:30 AM IST in summer
A Saturday 9 AM call from New York reaches India at 7:30 PM (winter) or 6:30 PM (summer) on Saturday, which suits most families.
Reaching an Indian bank, office or helpline
Most Indian offices work roughly 9:30 AM to 6 PM IST, Monday to Friday. In Eastern Time that is the middle of your night.
- Winter: 11 PM to 7:30 AM ET, starting the evening before
- Summer: midnight to 8:30 AM ET
The practical window is early morning in the US: a call at 7 AM EST still catches India before 6 PM.
Watching cricket from the US
The IPL runs from about late March to May, when New York is already on EDT, so the gap is 9½ hours.
- Evening matches, usually 7:30 PM IST = 10:00 AM EDT
- Afternoon matches, usually 3:30 PM IST = 6:00 AM EDT
On the West Coast, subtract three more hours: an evening match starts at 7 AM in Los Angeles.
Flying from New York to India
A nonstop flight from New York to Delhi or Mumbai takes about 14 to 16 hours. Add the 9½ or 10½ hour time difference and you arrive a calendar day later than you left: a plane leaving JFK at 8 PM on Monday in winter lands around 8:30 PM on Tuesday in Delhi, after roughly 14 hours in the air.
Coming back works the other way. Many return flights leave India late at night or in the early hours and land in New York the same morning by the calendar, because you gain those hours back. Arriving in India at night helps: go to bed at the local bedtime and let the first full day reset your body clock.
What changes for you in March and November
Only the US side moves. India stays on UTC+5:30 all year, so when you change your clocks, every recurring meeting you own lands an hour differently for your Indian colleagues.
If your calendar stores the meeting in “Eastern Time”, your side stays put and India’s side shifts. If the meeting was set up by someone in India in IST, the reverse happens: it stays fixed for them and moves an hour on your calendar. Agree which side the invite belongs to before the change weekend.
Eastern Time to India, every hour
Use the first India column from early November to mid-March, and the second for the rest of the year. Green rows are the calmest hours to reach India during your workday.
