About converting SGT to JST

Singapore Time (Singapore) and Japan Standard Time (Tokyo) 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 SGT box (or tap a quick preset) and read the JST 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.

SGT vs JST: the time difference through the year

The difference stays the same all year: JST is 1 h ahead of SGT.
