IST to BST Converter
Convert India Standard Time to British Time
Convert India Standard Time (IST) to British Time (BST) in one place. This free converter shows the current time in both zones, lets you turn any IST time into the matching BST time, and includes a full conversion table for the day. Right now BST is 4 hours and 30 minutes behind IST. British Time switches between Greenwich Mean Time (GMT) and British Summer Time (BST) across daylight saving.
Because it reads live time zone rules, the offset stays correct through daylight saving changes on either side, so you never have to work the difference out by hand. It is handy for scheduling calls and meetings, catching a live stream or match, or keeping in touch with family and colleagues across the two regions.
