Best times for calls between Eastern Time and India
There is no overlap between a 9-to-5 day in New York and a 9-to-6 day in India, so one side always stretches. The two usual options:
- US morning, India evening. 8:00–10:00 AM Eastern is 5:30–7:30 PM IST in summer (EDT) and 6:30–8:30 PM IST in winter (EST). This is the most common window for daily stand-ups between US and India teams.
- US evening, India morning. 9:00–10:30 PM Eastern is 6:30–8:00 AM IST in summer and 7:30–9:00 AM IST in winter. It suits quick check-ins before the Indian workday starts.
When the US changes its clocks in March and November, meetings fixed in Eastern Time move by an hour for people in India. India does not use daylight saving time.
Why “EST” is often wrong in summer
Strictly speaking, EST (UTC−5) is only used from early November to mid-March. The rest of the year New York is on EDT (UTC−4). Most people say “EST” all year round to mean New York time, so this converter uses the actual time on the date you pick. If a meeting invite says “10 AM EST” in July, it almost always means 10 AM New York time, which is 7:30 PM IST.
