About converting JST to IST
Japan Standard Time (Tokyo) and India Standard Time (India) are in different time zones, so a meeting, call or stream that's convenient in one may be early or late in the other. The clocks above update live and account for daylight saving automatically, so the time difference you see is the real one for today — not a fixed number that goes stale twice a year.
To plan across the two, type a time into the JST box (or tap a quick preset) and read the IST equivalent, including a "next day" or "previous day" note when the conversion crosses midnight. For any other pair of zones or cities, use the full timezone converter.
JST vs IST: the time difference through the year
The difference stays the same all year: IST is 3 h 30 min behind JST.
| Period | Difference |
|---|---|
| Oct 23, 2026 – Oct 23, 2027 | IST 3 h 30 min behind JST |
Daylight saving
Neither JST nor IST uses daylight saving, so this conversion never changes.

The two zones
Japan Standard Time is UTC+9 all year. Japan has not used daylight saving since 1951.
India Standard Time is UTC+5:30 all year — one of the few half-hour offsets. India uses a single time zone and has no daylight saving.
