EET to JST Converter

It takes three quick steps:

1. Click the EET 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.

JST is 7 hours ahead of EET. In everyday terms, once you know the time on one side you just add 7 hours to get the other — so a call between Athens and Tokyo is always 7 hours apart.

Right now the time in Japan Standard Time (JST) is Tuesday, June 30, 2026 · 2:53:59 AM. It ticks every second, so you’re always looking at the live JST clock.

And in Eastern European Time (EET), it’s currently Monday, June 29, 2026 · 7:53:59 PM. Compare the two and the 7 hours gap is easy to see.

For example, a 9:00 AM EET meeting takes place at 4:00 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.

The labels EET 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.

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