About converting JST to EST
Japan Standard Time (Tokyo) and Eastern Time (New York) 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 EST 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 EST: the time difference through the year
The gap between JST and EST changes during the year because only one of them uses daylight saving.
