IST to BST Converter

It takes three quick steps:

1. Click the IST field on the left and pick the time you want to convert.
2. The matching BST 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 is 1 hour behind IST. In everyday terms, once you know the time on one side you just subtract 1 hour to get the other — so a call between Jerusalem and London is always 1 hour apart.

Right now the time in British Summer Time (BST) is Monday, June 29, 2026 · 6:54:01 PM. It ticks every second, so you’re always looking at the live BST clock.

And in Israel Standard Time (IST), it’s currently Monday, June 29, 2026 · 7:54:01 PM. Compare the two and the 1 hour gap is easy to see.

For example, a 9:00 AM IST meeting takes place at 8:00 AM BST. 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.

The labels IST and BST 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.

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 IST to BST stays accurate for today and for any past or future date you type in.
