PST to JST Converter – Convert Pacific Time to Japan Time

JST is 17 hours ahead of PST, so to convert mentally, add 17 hours to your PST time. For example: 9:00 AM PST = 2:00 AM JST (next day). Our converter automatically adjusts for Daylight Saving Time so you always get the right result.

JST (Japan Standard Time, UTC+9) is 17 hours ahead of PST (Pacific Standard Time, UTC-8) during standard time. For example, 9:00 AM PST = 2:00 AM JST (next day). During DST periods, this difference changes by 1 hour when one or both zones observe Daylight Saving Time — our converter automatically applies the correct offset for any date you select.

JST is 17 hours ahead of PST, so standard 9–5 business hours do not overlap. The most practical window is early morning in PST (7–9 AM), which falls in the evening in JST — for example, 7:00 AM PST = 12:00 AM JST (next day). Use our meeting planner to find the exact time for your date, especially around DST transitions.

Yes. PST (Pacific Standard Time) observes Daylight Saving Time. Clocks spring forward to PDT (UTC-7) on the second Sunday in March, and fall back to PST on the first Sunday in November. During the DST period, the difference with JST changes by 1 hour. Our converter always uses the current offset for the date you select.

Major cities in the PST (Pacific Standard Time, UTC-8) timezone include: Los Angeles, San Francisco, Seattle, Portland, Las Vegas, Vancouver. These cities switch to PDT (UTC-7) from the second Sunday in March to the first Sunday in November.

Major cities in the JST (Japan Standard Time, UTC+9) timezone include: Tokyo, Osaka, Yokohama, Nagoya, Sapporo, Kyoto, Fukuoka. JST is a fixed-offset zone — these cities do not observe Daylight Saving Time.

JST is 17 hours ahead of PST. Because PST and JST are 17 hours apart, there is no standard business-hour overlap — plan for one side to take an early morning or late evening call. Always include both local times in calendar invites (for example, "2:00 PM PST / 7:00 AM JST (next day) JST"). Double-check around March and November (or March/October for European zones) when DST transitions can shift the offset by 1 hour.
