Below are the answers people search for most when converting Eastern Standard Time (EST) to India Standard Time (IST).
How does the EST to IST converter work?

- Click the EST field on the left and pick the time you want to convert.

- Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.
How many hours apart are EST and IST?
IST is 10 hours and 30 minutes ahead of EST. In everyday terms, once you know the time on one side you just add 10 hours 30 min to get the other — so a call between New York and Mumbai is always 10 hours 30 min apart.
What's the current time in IST?
Right now the time in India Standard Time (IST) is Monday, June 29, 2026 · 11:23:55 PM. It ticks every second, so you’re always looking at the live IST clock.
And what time is it in EST?
And in Eastern Standard Time (EST), it’s currently Monday, June 29, 2026 · 12:53:55 PM. Compare the two and the 10 hours 30 min gap is easy to see.
When is a good time to schedule a EST to IST meeting?
For example, a 9:00 AM EST meeting takes place at 7:30 PM IST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the EST–IST difference?
The labels EST and IST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this EST to IST conversion?
We don’t guess. EST and IST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Frequently asked questions
How many hours ahead of EST is IST?
IST is 10 hours and 30 minutes ahead of EST — a fixed 10 hours and 30 minutes difference, since both are fixed-offset labels.
What time is it in IST when it's 12:00 PM EST?
When it's 12:00 PM (noon) EST, it's 10:30 PM IST.
Do EST or IST use daylight saving time?
Eastern Standard Time (EST) observes daylight saving, alternating with EDT; India Standard Time (IST) is a fixed offset with no daylight saving.
Why might the real-world EST–IST difference change during the year?
The labels EST and IST are fixed offsets, so this converter is always exact. But Eastern Standard Time's region switches between standard and summer time, so for part of the year you may actually want EDT to IST. Always check which label a region is currently using before you schedule.
