About converting EST to JST

Eastern Time (New York) 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 EST 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.

EST vs JST: the time difference through the year

The gap between EST and JST changes during the year because only one of them uses daylight saving.

Frequently asked questions

6 answers
What is the time difference between EST 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 Eastern Time and Japan Standard Time, so the time you see is always right for right now.
How do I convert EST to JST?
Enter a time in the EST 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 EST to JST converter accurate with daylight saving?
Yes. It uses your browser's built-in time-zone database (the IANA zones behind New York 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 EST.
Does the EST to JST time difference change?
Yes. Over the next 12 months it is 13 h ahead or 14 h ahead, depending on the date — see the table of periods on this page.
What is a good meeting time for EST 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.
