What is the time difference between Tokyo and Vienna?

Tokyo (JST, UTC+9) is 8 hours ahead of Vienna during Central European Time (CET, UTC+1, roughly late October to late March) and 7 hours ahead during Central European Summer Time (CEST, UTC+2, roughly late March to late October).

Does Tokyo observe Daylight Saving Time?

No. Japan abolished Daylight Saving Time in 1952. Tokyo stays on JST (UTC+9) year-round, so the offset with Vienna changes only when Vienna switches between CET and CEST.

When does Vienna switch between CET and CEST?

Vienna (Austria) follows EU rules: clocks spring forward to CEST (UTC+2) on the last Sunday of March at 02:00 local time, and fall back to CET (UTC+1) on the last Sunday of October at 03:00 local time.

What are the best meeting times for Tokyo and Vienna?

Tokyo business hours 09:00–18:00 JST correspond to 01:00–10:00 CET (winter) or 02:00–11:00 CEST (summer) in Vienna. The best overlap is 16:00–18:00 Tokyo (08:00–10:00 Vienna in winter, or 09:00–11:00 in summer), where morning Vienna hours align with late afternoon Tokyo.

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. The DST transition dates are computed from the Europe/Vienna rules, so the offset shown reflects the current real-world difference.

What does JST stand for?

JST stands for Japan Standard Time. It is UTC+9, used across Japan year-round with no Daylight Saving adjustment.

What is CET and CEST?

CET is Central European Time (UTC+1), used by Vienna in winter. CEST is Central European Summer Time (UTC+2), used by Vienna from the last Sunday of March to the last Sunday of October.

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/Vienna time (CET UTC+1 in winter, CEST UTC+2 in summer).
The UTC offsets of both cities are compared: the difference is 8 hours in winter and 7 hours in summer.
Both clocks and the offset refresh every second in real time.
The converter lets you enter any Tokyo time and instantly see the equivalent Vienna time.
