WIT to JST Converter

It takes three quick steps:

1. Click the WIT field on the left and pick the time you want to convert.
2. The matching JST time updates on the right automatically — there’s no button to press.
3. Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.

There is no time difference. WIT and JST share the same UTC offset (UTC+9), so the two clocks always read exactly the same.

Right now the time in Japan Standard Time (JST) is Tuesday, June 30, 2026 · 2:54:02 AM. It ticks every second, so you’re always looking at the live JST clock.

And in Eastern Indonesian Time (WIT), it’s currently Tuesday, June 30, 2026 · 2:54:02 AM. Compare the two and the match is easy to see.

For example, a 9:00 AM WIT meeting takes place at 9:00 AM JST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.

The labels WIT and JST are fixed offsets, so the result on this page is always exact. Neither side changes its clocks for daylight saving, so the difference you see here is the same in summer and winter.

Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so WIT to JST stays accurate for today and for any past or future date you type in.
