When the difference changes
Central 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 – October 25, 2026Japan Standard Time is 7 hours ahead
- October 25, 2026 – March 28, 2027Japan Standard Time is 8 hours ahead
- March 28, 2027 – onwardsJapan Standard Time is 7 hours ahead
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Central European Time
Clocks go back one hour at 2am local time, becoming CET.
Japan Standard Time
Japan Standard Time stays on JST all year, so its offset from UTC never moves.
