What is WET in JST?

Japan Standard Time is 8 hours ahead

Western European Time is on UTC+1:00 and Japan Standard Time is on UTC+9:00 right now. Western European Time is on daylight saving, so its clocks read WEST. The gap changes during the year — see below.

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:

  1. Now – October 25, 2026Japan Standard Time is 8 hours ahead
  2. October 25, 2026 – March 28, 2027Japan Standard Time is 9 hours ahead
  3. March 28, 2027 – onwardsJapan Standard Time is 8 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

Sunday, October 25, 2026

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

Japan Standard Time

No clock changes

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

Scheduling between the two

Working hours overlap from 9:00 am to 10:00 am WEST, which is 5:00 pm to 6:00 pm JST. Anything inside that window falls in the normal working day at both ends.

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