When the difference changes

Japan Standard Time and Western European Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

  1. Now – March 28, 2027Western European Time is 9 hours behind
  2. March 28, 2027 – October 31, 2027Western European Time is 8 hours behind
  3. October 31, 2027 – onwardsWestern European Time is 9 hours behind

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Japan Standard Time

No clock changes

Japan Standard Time stays on JST all year, so its offset from UTC never moves.

Western European Time

Sunday, March 28, 2027

Clocks go forward one hour — 1:00 am becomes 2:00 am local time, and the zone is on WEST after that.

Scheduling between the two

There is no overlap between a nine-to-six working day in Tokyo and one in Lisbon — the gap is too wide. A call has to sit early or late for one side. Early morning in Tokyo is the usual compromise, since that is late afternoon or evening in Lisbon.

Western European Time (WET) is used in Portugal, Ireland and the Canary Islands
