EST to IST Time Zone Converter
This converts US Eastern Time — the New York and East Coast clock — into India Standard Time. India runs 10.5 hours ahead of the East Coast in winter and 9.5 hours ahead in summer, because the East Coast shifts for daylight saving while India never does. The converter picks the right gap for your date automatically, including that unusual half-hour.

Daylight saving is applied automatically for the date you pick. Labels like PST/EST name the zone (Pacific/Eastern); the real abbreviation shifts to PDT/EDT during daylight saving, and gmt here means London (GMT in winter, BST in summer) while utc stays fixed.
The time difference
India Standard Time is well ahead of US Eastern Time — 10.5 hours in winter and 9.5 hours in summer. India keeps one clock all year, while the East Coast springs forward to daylight time each spring. So the difference shrinks by an hour in the warmer months, not because India moved, but because the US did. The half hour comes from India's own offset, which sits on the :30 mark.
A worked example
Take 9:00 AM in New York. On January 15, 2026 that's 7:30 PM the same day in India. On July 15, 2026 the same 9:00 AM Eastern is 6:30 PM in India — an hour earlier, because the East Coast is on daylight time in July. Either way it's already evening in India while it's still morning on the East Coast.
Daylight saving & the abbreviation caveat
The slug says EST, the winter name, but the East Coast switches to EDT from spring to fall — locals just say "ET." India is the fixed side: IST never changes and has no daylight saving. That's why the gap swings between 10.5 and 9.5 hours depending on the date. The converter already knows which side of the US switch (March 8 and November 1, 2026) your date falls on, so the half-hour result is right without any mental math.
When you'll use it
Handy for scheduling calls with an India-based team or offshore developers, timing a handoff between US and Indian work hours, catching a live cricket match, or lining up a flight where times are quoted in local Indian time.
Frequently asked questions
How many hours ahead is India than the US East Coast?
10.5 hours in winter and 9.5 hours in summer. India doesn't change its clocks, so the gap only moves because the East Coast switches to daylight time from spring to fall.
Why is there a half hour in the gap?
India Standard Time sits on a half-hour offset from the world clock, so its difference with the US always ends in :30. That's why 9:00 AM in New York lands at 7:30 PM or 6:30 PM in India, not on the hour.
Does India observe daylight saving?
No. India Standard Time is fixed all year, so any change in the gap comes entirely from the US side switching for daylight saving.
