IST to EST Converter (India Time to Eastern Time)

Mid-January 2026: EST is 10 hours 30 minutes behind IST. Mid-July 2026: EDT is 9 hours 30 minutes behind IST.

Readers in India convert to Eastern Time when a US contact, university, employer or company announcement quotes the American clock. India Standard Time is UTC+05:30 all year, and Eastern Time is UTC-05:00 in winter and UTC-04:00 in summer, so the gap changes by an hour when New York changes its clocks.

Because the half-hour offset is not common in the US, a small mistake is easy to make: converting IST as if it were a whole-hour zone shifts the answer by thirty minutes. The tables here calculate the exact value for each Indian hour.

How to use this tool

1. Pick a date and time in IST. The date matters when daylight saving time is in force.
2. Read the matching time in EST, with both UTC offsets.
3. Use "Use current time" for now, or the tables below for a quick look.

Formula

EST time = IST time − (IST UTC offset) + (EST UTC offset)

The converter looks up both UTC offsets for the actual instant in the saved IANA time zone rules, so daylight saving changes are included automatically.

Example

Worked with the saved rules:

9:00 AM IST on March 2, 2026 = 10:30 PM EST (previous day)

6:30 PM IST on August 3, 2026 = 9:00 AM EDT

Time difference through the year

The difference depends on the date when either place moves its clocks. These are the offsets on two reference days, from the saved IANA rules:

Clock changes in 2026

Between these dates the difference shifts by the size of the change.

The Indian day seen from New York

Indian office hours of 9:30 a.m. to 6:00 p.m. fall between 11:00 p.m. and 7:30 a.m. in New York in winter. The best shared window is the Indian evening and the American morning. A 7:30 p.m. start in India is a 9:00 a.m. start in New York in winter.

Indian financial markets open at 9:15 a.m. IST and the regular session ends at 3:30 p.m. IST. In winter this equals 10:45 p.m. to 5:00 a.m. Eastern, so US observers see the session overnight.

Interviews, exams and visas

Students applying to US universities and professionals interviewing with American firms often get a time written in Eastern Time. Convert it twice, once for the date and once for the hour, since an afternoon interview in New York may be a late-night one in India.

Registration deadlines are worth the extra care. A form due at 11:59 p.m. Eastern closes at 10:29 a.m. in India on the next morning in winter, which leaves less time than the date suggests.
