For example, a 9:00 AM WET meeting takes place at 6:00 PM JST. Concretely, when Lisbon (WET) and Tokyo (JST) set up a call, jST is 9 hours ahead of WET.

This chart uses the fixed WET and JST offsets; the live converter above follows current daylight saving.

Convert WET to JST Time Zone

Everything you need for WET to JST — the difference, the current times, and how to plan around it.

How does the WET to JST converter work?

It takes three quick steps:

  1. Click the WET 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.

WET vs JST: what's the time gap?

JST is 9 hours ahead of WET. In everyday terms, once you know the time on one side you just add 9 hours to get the other — so a call between Lisbon and Tokyo is always 9 hours apart.

What time is it in JST right now?

Right now the time in Japan Standard Time (JST) is Tuesday, June 30, 2026 · 2:53:58 AM. It ticks every second, so you’re always looking at the live JST clock.

What time is it in WET right now?

And in Western European Time (WET), it’s currently Monday, June 29, 2026 · 5:53:58 PM. Compare the two and the 9 hours gap is easy to see.

When is a good time to schedule a WET to JST meeting?

For example, a 9:00 AM WET meeting takes place at 6:00 PM 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.

How does daylight saving affect WET to JST?

The labels WET and JST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.

Why can you trust this WET to JST converter?

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 WET to JST stays accurate for today and for any past or future date you type in.

Frequently asked questions

How many hours ahead of WET is JST?

JST is 9 hours ahead of WET — a fixed 9 hours difference, since both are fixed-offset labels.

What time is it in JST when it's 12:00 PM WET?

When it's 12:00 PM (noon) WET, it's 9:00 PM JST.

Do WET or JST use daylight saving time?

Western European Time (WET) observes daylight saving, alternating with WEST; Japan Standard Time (JST) is a fixed offset with no daylight saving.

Why might the real-world WET–JST difference change during the year?

The labels WET and JST are fixed offsets, so this converter is always exact. But Western European Time's region switches between standard and summer time, so for part of the year you may actually want WEST to JST. Always check which label a region is currently using before you schedule.
