How many hours ahead is New Delhi compared to New York?

New Delhi is either 9 hours 30 minutes or 10 hours 30 minutes ahead of New York. When New York observes EDT (UTC-4, roughly March through November), New Delhi (IST, UTC+5:30) is 9.5 hours ahead. When New York is on EST (UTC-5, roughly November through March), New Delhi is 10.5 hours ahead. New Delhi does not observe daylight saving time.

Does this tool account for daylight saving time?

Yes. The tool uses the browser's built-in Intl.DateTimeFormat API with the full IANA timezone identifiers (America/New_York and Asia/Kolkata), which automatically applies the correct DST offset for New York throughout the year. New Delhi stays on IST (UTC+5:30) year-round.

What time zone is New Delhi in?

New Delhi observes Indian Standard Time (IST), which is UTC+5:30. India does not use daylight saving time, so IST is constant all year across the entire country.

Why does New Delhi have a half-hour offset?

India chose UTC+5:30 when standardizing its time zone in 1947 to best fit the country geographically. The 30-minute offset is intentional, which is why the New York to New Delhi difference is always a half-hour increment (9.5 h or 10.5 h).

What is the best overlap window for New York and New Delhi business hours?

Overlap is very limited. When New York is on EDT, New Delhi business hours (9 AM-6 PM IST) correspond to roughly 11:30 PM-8:30 AM Eastern the previous day. Practical real-time windows are typically early morning New York paired with late evening New Delhi, or collaboration is handled asynchronously.

Does the clock use my local computer time?

Yes, it reads your device's system clock and converts it to both timezones. If your device clock is accurate, both displayed times will be accurate.

Summary

This tool displays live, side-by-side clocks for New York (America/New_York) and New Delhi (Asia/Kolkata). New Delhi observes Indian Standard Time (IST, UTC+5:30) year-round with no daylight saving time, while New York switches between EST (UTC-5) and EDT (UTC-4), so the offset is either 9 hours 30 minutes or 10 hours 30 minutes. The clocks update every second in your browser, and a built-in converter lets you translate any New York time to New Delhi or vice versa.

How it works

Your browser reads the current UTC timestamp every second.
It converts that timestamp into America/New_York local time using the Intl API.
It converts the same timestamp into Asia/Kolkata local time (IST, UTC+5:30).
Both clocks and the computed offset are rendered live on screen.
Enter any time in the converter panel to see the equivalent in the other city.
The offset adjusts automatically when New York switches between EST and EDT.
