In the graph below you see the time zone difference between Central European Time and Japan Standard Time. Drag the bubble to adjust the time and to see the corresponding time in the other time zone.
Central European Time is the time zone of most central European countries, and the Nordics, including cities like Paris, Berlin, Stockholm, Amsterdam, Madrid, Rome, Zurich and Warsaw. Japan Standard Time is the time zone of Japan, with places like Tokyo, Osaka, Sapporo, Nagoya and Fukuoka.
Usually it is preferable to schedule meetings before lunch for the person in CET and in the late afternoon for the person in JST.
CET is, as the name implies, the time zone for Central Europe. Important to note is that in summer Central European Time becomes CEST, which stands for Central European Summer Time. In practice, “Central” means “Western” as Central European Time includes everything from the Nordics to Spain. Note that Portugal and the UK are not on CET but instead observe GMT and that Eastern Europe (every country from Finland and South) observe Eastern European Time.
All countries in Western Europe, except Portugal and the UK, observe Central European Time. This includes Germany, Sweden, Italy, Spain, Croatia, Montenegro and Gibraltar to name a few.
The list is long but includes Berlin, Oslo, Madrid, Rome, Tirana, Amsterdam, Paris, Warsaw, Bern, Geneva and Copenhagen.
Daylight Saving Time is applied in Central Europe/Western Europe. CET in that case becomes CEST – Central European Summer Time and is one hour different. CEST is observed between the last Sunday of March and the last Sunday of October.
Japan Standard Time, or JST for short, is the standard time zone of Japan. It is 9 hours ahead of UTC. This also includes the islands of Okinawa even though they previously used a separate time zone. These days all of Japan runs on Japan Standard Time, from Hokkaido to Kyushu.
Japan is the only country using Japan Standard Time. It is however the same time as KST – Korean Standard Time and AWDT – Australian Western Daylight Time (i.e. when Western Australia applies Daylight Saving Time).
All cities in Japan applies JST, including Tokyo, Kyoto, Sapporo, Fukuoka, Hiroshima, Nagano and Nagoya.
DST (Daylight Saving Time) is currently not applied in Japan, although there have been attempts to re-introduce it. Especially the northern island of Hokkaido are in favor of DST as the sun rises very early in summer under the current system. Another argument to re-introduce DST has been that it would have a positive effect on emissions, but this has not been proven in any studies yet.
