Convert EST to IST Right Now
To convert from EST to IST, add 10 hours and 30 minutes. EST is UTC-5 and IST is UTC+5:30. The difference is 10.5 hours and 30 minutes.
Understanding the EST to IST Offset
EST (Eastern Standard Time) has a UTC offset of UTC-5. IST (Indian Standard Time) has a UTC offset of UTC+5:30. The net difference between these two zones is 10.5 hours and 30 minutes. When it is noon in EST, it is 10:30 PM in IST.
Daylight saving time note: EST observes DST (becomes EDT, UTC-4). IST does not observe DST. During DST periods, the offset between these zones may change by 1 hour. The table below shows standard time offsets.
The IANA timezone identifiers for these zones are America/New_York (EST) and Asia/Kolkata (IST). These identifiers are used by programming languages and operating systems to handle timezone conversions correctly, including automatic DST adjustments.

Code Examples
Python
from datetime import datetime
from zoneinfo import ZoneInfo
# Current time in EST
now_from = datetime.now(ZoneInfo("America/New_York"))
# Convert to IST
now_to = now_from.astimezone(ZoneInfo("Asia/Kolkata"))
print(f"EST: {now_from.strftime('%I:%M %p')}")
print(f"IST: {now_to.strftime('%I:%M %p')}")JavaScript
// Convert current time from EST to IST
const now = new Date();
const from = now.toLocaleString("en-US", { timeZone: "America/New_York" });
const to = now.toLocaleString("en-US", { timeZone: "Asia/Kolkata" });
console.log("EST:", from);
console.log("IST:", to);Go
package main
import (
"fmt"
"time"
)
func main() {
fromLoc, _ := time.LoadLocation("America/New_York")
toLoc, _ := time.LoadLocation("Asia/Kolkata")
now := time.Now().In(fromLoc)
converted := now.In(toLoc)
fmt.Printf("EST: %s\n", now.Format("3:04 PM"))
fmt.Printf("IST: %s\n", converted.Format("3:04 PM"))
}Frequently Asked Questions
What is the time difference between EST and IST?
EST (Eastern Standard Time) is UTC-5 and IST (Indian Standard Time) is UTC+5:30. The standard time difference is 10.5 hours and 30 minutes.
Does daylight saving time affect the EST to IST conversion?
Yes, EST observes DST and shifts to EDT (UTC-4) during summer months. IST does not observe DST. Always use IANA timezone identifiers in code to automatically handle these transitions.
What are the best overlap hours for EST and IST meetings?
For scheduling meetings between EST and IST, look for hours when both zones are in typical business hours (9 AM to 5 PM). When it is 9:00 AM in EST, it is 7:30 PM in IST. When it is 5:00 PM in EST, it is 3:30 AM (+1 day) in IST. The best overlap window depends on the specific zones and whether DST is active.
