About converting UTC to JST

Coordinated Universal Time (UTC) 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 UTC 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.

UTC vs JST: the time difference through the year

The difference stays the same all year: JST is 9 h ahead of UTC.

Daylight saving

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

The two zones

UTC · Coordinated Universal Time

Coordinated Universal Time (UTC) is the world's time standard, kept by atomic clocks. It never changes for daylight saving.

JST · Japan Standard Time

Japan Standard Time is UTC+9 all year. Japan has not used daylight saving since 1951.

Frequently asked questions

6 answers
What is the time difference between UTC and JST?
It's shown live at the top of this page (and it can change with daylight saving). The converter uses the current, DST-aware difference between Coordinated Universal Time and Japan Standard Time, so the time you see is always right for right now.
How do I convert UTC to JST?
Enter a time in the UTC box and the equivalent JST time appears instantly, adjusted for the current offset between the two zones — including a note if it lands on the previous or next day.
Is this UTC to JST converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind UTC and Tokyo), which tracks daylight-saving changes automatically, so the current times and difference are correct.
What time is it in Tokyo right now?
The live clock above shows the current time in Tokyo (JST), updating every second, alongside UTC.
Does the UTC to JST time difference change?
No. Neither switch changes the gap: JST is 9 h ahead of UTC all year.
What is a good meeting time for UTC and JST?
Standard 9-to-5 office hours don't overlap; early morning in one zone and evening in the other is the usual compromise — see the table on this page.
