EST to IST Converter (Eastern Time to India Time)

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

India Standard Time is UTC+05:30 and covers the entire country, from Delhi and Mumbai to Chennai and Kolkata. It is one of the few national times with a half-hour offset, and India does not use daylight saving time. Only the US side of this pair changes during the year.

The gap is large enough that the Indian date is usually a day later than the date in New York once evening begins. Software, finance and outsourcing teams that work between the two countries convert in this direction every day.

How to use this tool

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

Formula

IST time = EST time − (EST UTC offset) + (IST 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 EST on March 2, 2026 = 7:30 PM IST

6:30 PM EDT on August 3, 2026 = 4:00 AM IST (next day)

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.

Finding the overlap between New York and India

A New York morning is an Indian evening. A call at 9:00 a.m. Eastern Standard Time reaches Indian participants at 7:30 p.m., and a 10:00 a.m. start is 8:30 p.m. The late afternoon in New York is already past midnight in Delhi, so Indian staff who support the US often work an evening or night shift.

After the clocks move forward in the US, the gap narrows by an hour. From March 8 to November 1, 2026, New York is on EDT, and the same 9:00 a.m. call is 6:30 p.m. in India.

Holidays and calendars

India has gazetted national holidays on January 26 (Republic Day), August 15 (Independence Day) and October 2 (Gandhi Jayanti), and many religious festivals whose dates move each year, such as Diwali and Holi. The US observes its own set of federal holidays. Before setting a deadline, check both calendars.

When writing a date in a message between the two places, write the month in words and name the time zone. A time near midnight in India can fall on the previous or next date in New York.
