EST is UTC−05:00; EDT is UTC−04:00. The converter automatically uses the offset for the selected date.
How to use this tool
- Choose the source and destination time zones.
- Enter the source date and local time; the date matters for seasonal offsets.
- Convert and check both the destination time and date.
Formula & method
IANA time-zone rules convert the entered wall-clock time to an instant and format it in the destination zone. India uses Asia/Kolkata; New York uses America/New_York and changes between standard and daylight time. Nonexistent or ambiguous local times produce an explanation.
A practical example
Noon in India is 01:30 in New York during standard time and 02:30 during daylight time. Choose a specific date to get the correct offset.
When this tool is useful
Plan a meeting between India and New York or compare another supported pair of time zones. A date-specific conversion helps avoid assuming that the difference stays constant throughout the year.
Common mistakes and limitations
- New York alternates between standard and daylight time, so the page title is not a fixed-offset promise.
- The destination can be on the previous or next calendar day; share the date as well as the time.
Frequently asked questions
Why does the India–New York difference change?
India uses a fixed offset while New York observes daylight saving. The converter uses the selected date with named time-zone rules to choose the relevant offset.
What happens during a clock change?
Some local times are skipped or occur twice. The tool explains ambiguous or nonexistent times rather than treating a clock reading as unambiguous. Verify a critical appointment with its organizer.
