Scheduling from New York for India
India Standard Time is 10 hours 30 minutes ahead of New York in January and 9 hours 30 minutes ahead in July. So 9:00 AM in New York is 7:30 PM in India in January and 6:30 PM in July. Enter your Eastern time, or press Use now, and the India time appears.
The hour changes because New York moves its clocks and India does not. In spring, when New York moves to EDT, the gap closes by an hour. In autumn it widens again. If you book regular calls with a team in Bangalore, Delhi or Mumbai, a standing time in your calendar can drift by an hour for them twice a year.
A New York team with partners in India has a good morning and a poor afternoon. Eastern 8:00 PM is 6:30 AM in India the next morning in January, so late calls become early ones. In the other direction, Eastern 9:00 AM is already evening in India, and a 2:00 PM Eastern call in January falls at 12:30 AM. The hour-by-hour table lays a 9:00 to 17:00 Eastern day on the India clock to show the full spread.
The result tells you when the date has moved, which matters for the late New York evening slots. Press swap if you need to start from the India time instead.

Questions about this tool
What is the time difference between New York and India?
10.5 hours in winter and 9.5 hours in summer, with India ahead. It changes because only New York uses daylight saving.
Which New York hours work for a call with India?
Early morning Eastern is evening in India. 9:00 AM Eastern is 7:30 PM in India in January and 6:30 PM in July, and the hour-by-hour table shows the rest.
Is the half hour a mistake?
No. India Standard Time is UTC+5:30, so results end in :30 when the New York time ends in :00.
