About IST to EST
This page converts India Standard Time (IST) to Eastern Time (ET). Pick a date and time, and the answer appears at once. Below it, a table shows every hour of that day.
ET is 10 hours 30 minutes behind IST in winter, and 9 hours 30 minutes behind in summer, while the US is on daylight saving time. For example, 9:00 AM IST is 10:30 PM EST (previous day) in winter and 11:30 PM EDT (previous day) in summer.
IST is the time in Delhi, Mumbai, Bengaluru, Chennai, Hyderabad and Kolkata — all of India. ET is the time in New York, Washington DC, Miami, Atlanta, Boston and Toronto.
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
India Standard Time (IST, UTC+5:30) has no daylight saving time. It stays the same all year.
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.
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.
