How this works
Method
Here IST means India Standard Time, UTC+5:30 all year; EST means Eastern Time, EST (UTC−5) in its winter and EDT (UTC−4) in its summer, as kept in New York. So EST is 10 h 30 min behind IST, and EDT is 9 h 30 min behind. Two 9-to-5 working days do not overlap at all, so one side has to start early or stay late. Full method

How to convert IST to EST
Here IST means India Standard Time, UTC+5:30 all year; EST means Eastern Time, EST (UTC−5) in its winter and EDT (UTC−4) in its summer, as kept in New York. So EST is 10 h 30 min behind IST, and EDT is 9 h 30 min behind. Two 9-to-5 working days do not overlap at all, so one side has to start early or stay late.
From India, Eastern Time matters for anyone working with New York, New Jersey, Washington or Toronto: back-office and IT teams, students with East Coast universities, and families following a relative’s day. The US East Coast wakes up as the Indian working day ends, so an Indian evening, roughly 6:30 pm to 9:30 pm, is the natural window for live meetings.
When you read a US time, check whether it is Eastern or Pacific: they differ by three hours, and US companies often quote Eastern for nationwide events such as product launches and TV broadcasts. The page converts to the clock New York actually uses on that date, EST in winter or EDT in summer, so you don’t have to work out which one applies. For dates in mid-March or early November, convert the specific day, because the US switches on a Sunday and the gap changes overnight.
Rule of thumb: Take away 10½ hours from Indian time in winter or 9½ hours in summer: 8:00 pm in Mumbai is 9:30 am (EST) or 10:30 am (EDT) in New York.
EST = IST −10:30 · EDT = IST −9:30

Meeting planner: best times for IST and EST
The IST and EST working days never overlap, so every meeting asks one side to start early or stay late. The shaded runs are the hours when both clocks are between 7 am and 9 pm; pick the end that suits whoever has the more flexible day, and swap it now and then.
January: IST and EST
- No hour is inside 9 to 5 on both clocks.
- Early or late for one side: 7:00 am to 7:30 am IST is 8:30 pm to 9:00 pm EST the day before (30 min); 5:30 pm to 9:00 pm IST is 7:00 am to 10:30 am EST (3 h 30 min).
July: IST and EDT
- No hour is inside 9 to 5 on both clocks.
- Early or late for one side: 4:30 pm to 9:00 pm IST is 7:00 am to 11:30 am EDT (4 h 30 min).

Frequently Asked Questions
What is 9 am IST in EST?
In January, 9:00 am IST is 10:30 pm EST the day before. In July, 9:00 am IST is 11:30 pm EDT the day before.
What time is 7 pm IST in EST?
In winter 7:00 pm in India is 8:30 am in New York (EST). Between mid-March and early November, when New York is on EDT, it is 9:30 am. Both fall on the same calendar date as in India.
Does India change its clocks when the US does?
No. India has stayed on UTC+5:30 all year since 1945. Only the US side moves, which is why a recurring call set in Eastern time appears an hour earlier on Indian calendars from mid-March to early November.
