In the graph below you see the time zone difference between Eastern Standard Time and Japan Standard Time. Drag the bubble to adjust the time and to see the corresponding time in the other time zone.
Eastern Standard Time is the time zone of the Canadian and US East Coast, including cities like Montreal, Ottawa, New York, Washington D.C. And Miami. 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 in the early morning, or late evening for the person in EST and in the evening, or early morning for the person in JST.
This is the standard time of the Eastern US, Canada and parts of the Caribbean. It is in most places observed only in the winter months, from November to March. The origin of EST is the same as for most time zones – it was introduced when the railroad was built across the United States. It is important to note that there is also Eastern Standard Time in Australia, but this is usually called AEST and thus not to be confused with EST.
Most of the Eastern seaboard of the US observe EST, as well as most locations in Eastern Canada although there are a few exceptions. Locations such as New York, Washington, Quebec and Ontario are all on Eastern Standard Time. Also some Caribbean locations such as Jamaica, Haiti and Panama are in this time zone.
It is important to note that with the exception of Panama, Jamaica and a couple of locations in Canada and the US most in this time zone do observe DST and thus switch to EDT in the summer. As always, it is better to look up the actual location than the timezone itself.
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.
