When the difference changes

Pacific 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 14, 2027Japan Standard Time is 17 hours ahead
March 14, 2027 – November 7, 2027Japan Standard Time is 16 hours ahead
November 7, 2027 – onwardsJapan Standard Time is 17 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.

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on PDT after that.

No clock changes

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