EST to IST Converter – Convert Eastern Time to Indian Time

To convert EST to IST, add 10 hours and 30 minutes to Eastern Standard Time. For example, when it's 9:00 AM in New York (EST), it's 7:30 PM in Mumbai (IST). During Daylight Saving Time (EDT), IST is 9 hours and 30 minutes ahead. Use our converter above for instant, accurate conversions.

IST is 10 hours and 30 minutes ahead of EST. During Daylight Saving Time (March to November), when the US switches to EDT, the difference becomes 9 hours and 30 minutes. India does not observe Daylight Saving Time, so IST remains constant year-round at UTC+5:30.

The best meeting time between New York and India is typically 9:00 AM EST (7:30 PM IST) or 8:00 PM EST (6:30 AM IST next day). For team calls between US East Coast and Indian cities like Mumbai, Delhi, or Bangalore, early morning EST (evening IST) or late evening EST (early morning IST) works best for overlapping business hours.

Yes, the US East Coast observes Daylight Saving Time. Clocks spring forward on the second Sunday in March (EST becomes EDT) and fall back on the first Sunday in November. During EDT, the time difference with India reduces from 10.5 hours to 9.5 hours, affecting meeting schedules between New York and Mumbai.

Major cities in EST include New York City, Boston, Philadelphia, Washington DC, Miami, Atlanta, and Toronto. All these cities observe Eastern Time, switching between EST (winter) and EDT (summer) during Daylight Saving Time transitions.

All of India follows IST (Indian Standard Time), including Mumbai, Delhi, Bangalore, Hyderabad, Chennai, Kolkata, Pune, and Ahmedabad. India does not observe Daylight Saving Time, so IST remains UTC+5:30 throughout the year, making time conversions with EST/EDT more predictable.

For calls between New York and Mumbai, schedule early morning EST (9-11 AM, which is 7:30-9:30 PM IST) or late evening EST (8-10 PM, which is 6:30-8:30 AM IST next day). Always include both time zones in meeting invites: "9:00 AM EST / 7:30 PM IST". Remember that from March to November, EDT is in effect, reducing the time difference to 9.5 hours instead of 10.5 hours.
