Questions people ask
Is it 9 hours 30 minutes or 10 hours 30 minutes?
Both, depending on the date. The US is on daylight saving time from March 8 to November 1, 2026 and March 14 to November 7, 2027; in those months the gap is 9 hours 30 minutes. The rest of the year it is 10 hours 30 minutes. India stays on IST (UTC+5:30) all year.
People say EST all year. Is that right?
In everyday use, "EST" often just means Eastern time. Strictly, EST is the winter name and EDT is the summer one. The converter above uses the right one for the date you pick.
What's a good time for a call between India and the US?
Early morning in New York is evening in India. For example, 8:00 AM EDT is 5:30 PM IST. Use the meeting planner to find times inside everyone's working hours.
