A quick guide to IST → IST: the time gap, the live clocks, scheduling tips, and how we keep it accurate.

How does the IST to IST converter work?

It takes three quick steps:

  1. Click the IST field on the left and pick the time you want to convert.
  2. The matching IST time updates on the right automatically — there’s no button to press.
  3. Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.

What is the time difference between IST and IST?

IST is 3 hours and 30 minutes ahead of IST. In everyday terms, once you know the time on one side you just add 3 hours 30 min to get the other — so a call between Jerusalem and Mumbai is always 3 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 · 11:24:01 PM. It ticks every second, so you’re always looking at the live IST clock.

And what time is it in IST?

And in Israel Standard Time (IST), it’s currently Monday, June 29, 2026 · 7:54:01 PM. Compare the two and the 3 hours 30 min gap is easy to see.

Planning a meeting across IST and IST?

For example, a 9:00 AM IST meeting takes place at 12:30 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 IST–IST difference?

The labels IST 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 IST to IST conversion?

We don’t guess. IST 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 IST is IST?

IST is 3 hours and 30 minutes ahead of IST — a fixed 3 hours and 30 minutes difference, since both are fixed-offset labels.

What time is it in IST when it's 12:00 PM IST?

When it's 12:00 PM (noon) IST, it's 3:30 PM IST.

Do IST or IST use daylight saving time?

Israel Standard Time (IST) observes daylight saving, alternating with IDT; India Standard Time (IST) is a fixed offset with no daylight saving.

Why might the real-world IST–IST difference change during the year?

The labels IST and IST are fixed offsets, so this converter is always exact. But Israel Standard Time's region switches between standard and summer time, so for part of the year you may actually want IDT to IST. Always check which label a region is currently using before you schedule.
