JST to IST Converter
Convert Japan Standard Time to India Standard Time
Convert Japan Standard Time (JST) to India Standard Time (IST) in one place. This free converter shows the current time in both zones, lets you turn any JST time into the matching IST time, and includes a full conversion table for the day. Right now IST is 3 hours and 30 minutes behind JST.
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.
