About converting JST to GST

Japan Standard Time (Tokyo) and Gulf Time (Dubai) (Dubai) 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 GST 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 GST: the time difference through the year

The difference stays the same all year: GST is 5 h behind JST.

Daylight saving

Neither JST nor GST uses daylight saving, so this conversion never changes.
