IST to EST time
EST is 10 hours 30 minutes behind IST.
Time difference between IST and EST
EST is 10 hours 30 minutes behind IST. IST is on India Standard Time (UTC+05:30) and EST is on Eastern Standard Time (EST (UTC−05:00)).
The gap is not constant. Because of daylight saving it varies from 9 hours 30 minutes to 10 hours 30 minutes over the year.
Convert IST time to EST time
These examples use the current offsets, UTC+05:30 for IST and UTC−05:00 for EST. Use the converter above for any other time or date.
EST is behind, so from midnight to 10:30 AM in IST it is still the previous calendar day in EST.
| IST time | EST time |
|---|---|
| 6:00 AM | 8:30 PM (previous day) |
| 9:00 AM | 11:30 PM (previous day) |
| 12:00 PM | 1:30 AM |
| 3:00 PM | 4:30 AM |
| 6:00 PM | 7:30 AM |
| 9:00 PM | 10:30 AM |
Best time to call or meet: IST and EST working hours
The standard 9:00 AM to 5:00 PM working days in IST and EST do not overlap.
Between 8:00 AM and 8:00 PM, both cities are awake from 6:30 PM to 8:00 PM in IST (8:00 AM to 9:30 AM in EST), which usually means an early start or a late finish for one side.
Weekends, public holidays and local working weeks differ by country, so check those before booking.
Daylight saving time in India Standard Time and Eastern Time
India Standard Time does not change its clocks for daylight saving, so its UTC offset stays the same all year.
Eastern Time observes daylight saving time. Its next change is on Mar 14, 2027 at 2:00 AM, when clocks go forward 1 hour (UTC−05:00 to UTC−04:00).
