What is the time difference between Tokyo and Frankfurt?

Tokyo (JST, UTC+9) is 8 hours ahead of Frankfurt when Frankfurt is on CET (UTC+1, roughly late October to late March), and 7 hours ahead when Frankfurt observes CEST (UTC+2, roughly late March to late October).

Does Tokyo observe Daylight Saving Time?

No. Japan abolished Daylight Saving Time in 1952 and has not used it since. Tokyo stays on JST (UTC+9) year-round.

Does Frankfurt observe Daylight Saving Time?

Yes. Frankfurt (and the rest of Germany) switches to CEST (UTC+2) on the last Sunday of March and returns to CET (UTC+1) on the last Sunday of October. This means the Tokyo-Frankfurt offset changes between 7 and 8 hours depending on the time of year.

What are the best meeting times for Tokyo and Frankfurt?

Tokyo business hours 09:00-18:00 JST correspond to 01:00-10:00 CET (02:00-11:00 CEST) in Frankfurt. The only reasonable overlap is 16:00-18:00 Tokyo (08:00-10:00 Frankfurt in summer / 07:00-09:00 in winter), where Frankfurt is just starting and Tokyo is finishing the work day.

Is this tool accurate for scheduling?

Yes. It uses the IANA timezone database embedded in your browser, which includes all historical and future DST transitions for Europe/Berlin. Accuracy depends on your device clock being synchronized via NTP, which most devices do automatically.

What does CET stand for?

CET stands for Central European Time (UTC+1), used by Frankfurt and Germany in winter. CEST stands for Central European Summer Time (UTC+2), used during daylight saving months from late March to late 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/Berlin time, which covers Frankfurt (CET UTC+1 in winter, CEST UTC+2 in summer).
The UTC offsets of both cities are compared: 8 hours difference in winter, 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 Frankfurt time.
