EST to IST Time Converter
Content updated .
This page converts Eastern Time (EST) to India Standard Time (IST). India is 10 hours 30 minutes ahead of New York when New York is on EST (around January), and 9 hours 30 minutes ahead of when it is on EDT (around July). Daylight saving time changes one or both UTC offsets. These are seasonal examples, not a rule for every date.
Select the actual event date and time above. This page follows the city zones America/New_York and Asia/Kolkata, not a permanently fixed abbreviation. For example, EST is UTC−5 but New York uses EDT (UTC−4) during daylight saving; PST and PDT likewise differ by an hour. BST means British Summer Time, while London uses GMT in winter. IST on these pages means India Standard Time, not Irish or Israel time.
Daylight saving time (DST, sometimes called daylight savings) can alter a meeting's time difference. Different countries may switch on different weekends, or not switch at all. January and July tables are examples: use a dated conversion around the transition weeks and check the displayed abbreviations.

The time difference
| Conversion | Add to EST |
|---|---|
| EST to IST | +10:30 |
| EDT to IST | +9:30 |
Destination time = source time + destination UTC offset − source UTC offset (for the event date).
If the result passes midnight, the date moves forward (or back) by a day. The converter above shows the day change explicitly.

Best times for a meeting between New York and India
These sample hours fall between 9 AM and 6 PM in both cities on the table dates. Confirm each occurrence of a recurring meeting, especially during March, April, October and November:
When New York is on EST: there is no overlap between 9 AM and 6 PM in both zones. One side has to take an early or late call.
When New York is on EDT: there is no overlap between 9 AM and 6 PM in both zones. One side has to take an early or late call.
Clock changes, repeated times and time-zone data
A forward clock change skips some local times; a backward change repeats them. If your event falls in the repeated hour, confirm which UTC offset the organiser means. Avoid assuming that a local time alone identifies one instant. Future government decisions can change the rules, and an outdated browser can have outdated time-zone data.

Frequently asked questions
What is the time difference between EST and IST?
India is 10 hours 30 minutes ahead of New York when New York is on EST (around January), and 9 hours 30 minutes ahead of when it is on EDT (around July). Daylight saving time changes one or both UTC offsets. These are seasonal examples, not a rule for every date.
How does daylight saving affect this conversion?
The calculator follows the dated rules for America/New_York and Asia/Kolkata. A zone may change its UTC offset for summer, while another may not. India and UTC do not currently observe DST; New York, Chicago, Los Angeles and London do. Check the selected date rather than treating an abbreviation or one seasonal sample as a year-round offset.
What time is 9 AM EST in IST?
9:00 AM EST is 7:30 PM IST, and 9:00 AM EDT is 6:30 PM IST.
How do I convert a different date or time?
Enter the date and time at the top of this page. The converter uses your browser's time zone database, so it applies the correct offset for that specific date, including the weeks around clock changes.
