Time Difference: India and USA
The US East Coast is 10 hours 30 minutes behind India in winter and 9 hours 30 minutes behind in summer. 8:00 PM in India is 9:30 AM on the East Coast on EST and 10:30 AM on EDT.
Daylight saving note: India never changes its clocks. The US East Coast is 10 hours 30 minutes behind during EST and 9 hours 30 minutes behind during EDT, which runs from the second Sunday in March to the first Sunday in November.
Counting Back From India to the US East Coast
India runs on UTC+5:30 all year, and the US East Coast runs on UTC-5 in winter and UTC-4 in summer. Seen from India, the East Coast is 10 hours 30 minutes behind on EST and 9 hours 30 minutes behind on EDT.
The mental method is to take off ten and a half hours in winter or nine and a half in summer. 8:00 PM in India becomes 9:30 AM in winter and 10:30 AM in summer, the same morning on the East Coast.
Only the US moves. The Indian side of a recurring call stays at the same IST hour all year, while the East Coast hour changes by one at the March and November clock changes.

The India-USA Call Window
The workable overlap is India's evening and the East Coast's morning. 7:00 PM to 9:00 PM in India is 8:30 AM to 10:30 AM on the East Coast on EST, and 9:30 AM to 11:30 AM on EDT. India's own morning is the previous evening in the US: 9:00 AM IST is 10:30 PM the previous day on EST.
Avoiding India-New York Time Mistakes
New York is behind, so an early morning in India is still the previous calendar day in New York. With a 10 hours 30 minutes gap, that applies to anything before 10:30 AM in India: 10:00 AM there is 11:30 PM the previous day in New York. When the gap narrows to 9 hours 30 minutes, the cut-off moves to 9:30 AM.
Mind the date. India's 9:00 AM on a Tuesday is 10:30 PM the previous day on the East Coast on EST, so it's still Monday there. A deadline "by Monday" in India has already passed in the US by the time it's Tuesday morning in India, so state the time zone with the date. Going the other way, 9:00 AM Eastern is 7:30 PM in India.
A Worked Example: An India Evening Stand-Up With the East Coast
Say an India team holds a stand-up at 8:30 PM IST. The East Coast joins at 10:00 AM on EST and 11:00 AM on EDT, a normal start to its morning. If the East Coast hosts at 8:00 AM, India joins at 6:30 PM on EST and 5:30 PM on EDT.
After the second Sunday in March the East Coast time of the same India-hosted stand-up is an hour later, and after the first Sunday in November it is an hour earlier. India's side never moves.
