When the difference changes
Western European Time and Japan Standard 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:
- Now – March 28, 2027Japan Standard Time is 9 hours ahead
- March 28, 2027 – October 31, 2027Japan Standard Time is 8 hours ahead
- October 31, 2027 – onwardsJapan Standard Time is 9 hours ahead
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
Western European Time
Clocks go forward one hour — 1:00 am becomes 2:00 am local time, and the zone is on WEST after that.
Japan Standard Time
Japan Standard Time stays on JST all year, so its offset from UTC never moves.

Scheduling between the two
There is no overlap between a nine-to-six working day in Lisbon and one in Tokyo — the gap is too wide. A call has to sit early or late for one side. Early morning in Lisbon is the usual compromise, since that is late afternoon or evening in Tokyo.
Western European Time (WET) is used in Portugal, Ireland and the Canary Islands
