IST and EST: quick answers
Is Eastern Time ahead of or behind India?
Eastern Time is 10½ hours behind India right now. That changes on Sunday, March 14, 2027, when it becomes 9½ hours behind India.
Does daylight saving change the India–Eastern Time difference?
Yes. Only Eastern Time changes its clocks; India doesn’t use daylight saving time. Over the next year the difference is 10½ hours now, then 9½ hours from March 14. The converter above applies these changes for any date you pick.
What’s the best time for a call between India and Eastern Time?
Normal 8 AM–5 PM working days don’t overlap. The least painful option is 5:30 PM–10:00 PM in India, which is 7:00 AM–11:30 AM in Eastern Time: early or late for one side, but inside 7 AM–10 PM for both. For a regular meeting, consider rotating the time (times for today; they move with daylight saving changes).
