EST to IST

About EST to IST

This page converts Eastern Time (ET) to India Standard Time (IST). Pick a date and time, and the answer appears at once. Below it, a table shows every hour of that day.

IST is 10 hours 30 minutes ahead of ET in winter, and 9 hours 30 minutes ahead in summer, while the US is on daylight saving time. For example, 9:00 AM ET is 7:30 PM IST in winter and 6:30 PM IST in summer.

ET is the time in New York, Washington DC, Miami, Atlanta, Boston and Toronto. IST is the time in Delhi, Mumbai, Bengaluru, Chennai, Hyderabad and Kolkata — all of India.

The converter uses your browser's own time zone data, so daylight saving is handled for you — always right for the date you pick, in the past or the future.

Daylight saving time

Eastern Time uses EST (UTC−5) in winter and EDT (UTC−4) in summer. The US clocks go forward on the second Sunday of March and back on the first Sunday of November: March 8, 2026 to November 1, 2026, and March 14, 2027 to November 7, 2027.

India Standard Time (IST, UTC+5:30) has no daylight saving time. It stays the same all year.

Good to know

• EST or ET? Strictly, EST is only the winter time of the US East Coast; in summer it is EDT. Many people say "EST" all year when they mean "East Coast time". This page uses the real clock time for the date you pick, so the answer is right either way.
• IST is half an hour off the usual whole-hour zones (UTC+5:30), so a full hour on one side is half past the hour on the other.
• Planning a meeting? Pick the date and time, then add the other cities of the people you meet with. Everyone's time shows in one list.
• The answer comes from your device's time zone data. Nothing is sent anywhere.
