Daylight saving — the fine print

IST never changes — only New York's clocks move. In 2026 the US springs forward on 8 March and falls back on 1 November.

IST to EST converter — how the conversion works

How far ahead is IST from EST?

India is 10 hours 30 minutes ahead of New York in winter (EST, UTC−05:00) and 9 hours 30 minutes ahead in summer (EDT, UTC−04:00). IST never moves — it is fixed at UTC+05:30 — so the whole change comes from the New York side.

EST vs EDT — which one applies?

Use EST from the first Sunday in November to the second Sunday in March, and EDT the rest of the year. In 2026 that means EST until 8 March, EDT until 1 November, then EST again. Pick a date above and the converter labels the right one.

The two days a year that break naive converters

On 8 March 2026, 02:00–02:59 never happens in New York — clocks jump from 01:59 EST to 03:00 EDT. On 1 November 2026, 01:00–01:59 happens twice. This converter flags both cases and shows the nearest valid time, or both occurrences.

IST means India here — not Ireland or Israel

“IST” is three different time zones' abbreviation. Every abbreviation on this page is shown with its full IANA name and UTC offset, so IST — Asia/Kolkata — UTC+05:30 can never be mistaken for Dublin.

Finding a time that works for both sides

With default 09:00–17:00 working hours on both sides there is no overlap between India and New York — India's working day ends two and a half hours before New York's starts. The meeting finder says so honestly and shows the closest near-overlap.

Frequently asked questions

What time is it in EST when it is noon in IST?

It depends on the date. In winter (EST, UTC−05:00) noon IST is 01:30 EST the same day. In summer (EDT, UTC−04:00) noon IST is 02:30 EDT the same day. The gap is 10h 30m in winter, 9h 30m in summer.

Does IST observe daylight saving time?

No. India Standard Time (IST, Asia/Kolkata) is fixed at UTC+05:30 all year and has never observed daylight saving time. Only the New York side changes, between EST and EDT.

What is the difference between EST and EDT?

EST (UTC−05:00) is New York's winter time; EDT (UTC−04:00) is its summer time. In 2026 clocks spring forward on 8 March and fall back on 1 November.

What happens at 2:30 AM on 8 March 2026 in New York?

That time does not exist — clocks jump from 02:00 EST straight to 03:00 EDT. This converter tells you so and offers the nearest valid times (01:59 EST and 03:00 EDT) instead of silently shifting your meeting.

Is IST India or Ireland?

Both — which is why this page never shows a bare “IST”. Here IST means India Standard Time, Asia/Kolkata, UTC+05:30. Ireland's IST is Irish Standard Time (Europe/Dublin, summer only).

Is my data uploaded anywhere?

No. All conversion happens in your browser using its built-in time zone database. Your times and zone choices are never sent anywhere — the only network request is the site's own analytics tag, which counts page views. Only your last-used zone pair is saved, in your own browser's local storage.
