What is the time difference between Tokyo and Helsinki?

Tokyo (JST, UTC+9) is 7 hours ahead of Helsinki in winter (EET, UTC+2) and 6 hours ahead in summer (EEST, UTC+3). Japan does not observe Daylight Saving Time, so the gap shifts only when Finland moves its clocks in spring and autumn.

Does Tokyo observe Daylight Saving Time?

No. Japan abolished DST in 1952 and has not used it since. Tokyo stays on JST (UTC+9) all year. Only Helsinki shifts its clocks twice a year, which is why the Tokyo-Helsinki gap alternates between 6 and 7 hours.

When does Finland switch between EET and EEST?

Finland moves clocks forward to EEST (UTC+3) on the last Sunday in March at 03:00 EET. At that point Tokyo goes from 7 hours ahead to 6 hours ahead. Clocks move back to EET (UTC+2) on the last Sunday in October at 04:00 EEST, returning the gap to 7 hours.

What are the best meeting times when calling from Tokyo to Helsinki?

In winter (EET), Tokyo at 16:00–17:00 JST equals Helsinki at 09:00–10:00. In summer (EEST), Tokyo at 15:00–16:00 JST equals Helsinki at 09:00–10:00. Either way, early afternoon Tokyo time gives the best Helsinki morning overlap.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser — the same source used by operating systems and calendar apps worldwide. Accuracy depends on your device clock being synchronized via NTP, which most devices handle automatically.

What is EET and EEST?

EET (Eastern European Time) is UTC+2 and is used by Finland in winter. EEST (Eastern European Summer Time) is UTC+3 and is active from late March to late October. Helsinki switches between the two each year.

How it works

Your browser reads the current moment from your device clock.
It converts that moment to Asia/Tokyo time (JST, UTC+9) using the IANA timezone database built into modern browsers.
The same moment is converted to Europe/Helsinki time (EET or EEST depending on the season).
The UTC offsets of both cities are compared to calculate the exact hour difference.
All three values — Tokyo time, Helsinki time, and the offset — refresh every second.
When Helsinki switches between EET and EEST, the displayed offset adjusts automatically between +6 and +7 hours.
