Convert BST to IST Time Zone

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

How does the BST to IST converter work?

It takes three quick steps:

  1. Click the BST 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.

BST vs IST: what's the time gap?

IST is 1 hour ahead of BST. In everyday terms, once you know the time on one side you just add 1 hour to get the other — so a call between London and Jerusalem is always 1 hour apart.

What time is it in IST right now?

Right now the time in Israel Standard Time (IST) is Monday, June 29, 2026 · 7:53:59 PM. It ticks every second, so you’re always looking at the live IST clock.

What time is it in BST right now?

And in British Summer Time (BST), it’s currently Monday, June 29, 2026 · 6:53:59 PM. Compare the two and the 1 hour gap is easy to see.

Planning a meeting across BST and IST?

For example, a 9:00 AM BST meeting takes place at 10:00 AM 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.

How does daylight saving affect BST to IST?

The labels BST and IST are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 1 hour gap usually holds steady right through the year.

Why can you trust this BST to IST converter?

Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so BST to IST stays accurate for today and for any past or future date you type in.

Frequently asked questions

How many hours ahead of BST is IST?

IST is 1 hour ahead of BST — a fixed 1 hour difference, since both are fixed-offset labels.

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

When it's 12:00 PM (noon) BST, it's 1:00 PM IST.

Do BST or IST use daylight saving time?

British Summer Time (BST) observes daylight saving, alternating with GMT; Israel Standard Time (IST) observes daylight saving, alternating with IDT.

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

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