About these time zones
Japan Standard Time (JST)
Japan Standard Time (JST) is UTC+9 all year across the whole of Japan. Japan has not observed daylight saving time since 1951. JST shares its offset with Korea Standard Time.
Pacific Standard Time (PST)
Pacific Standard Time (PST) is UTC-8. California, Washington, most of Oregon and Nevada, most of British Columbia and Baja California use PST in winter and Pacific Daylight Time (PDT, UTC-7) from the second Sunday in March to the first Sunday in November. Yukon left Pacific Time in 2020 and now stays on UTC-7 all year.
JST to PST FAQs
What time is it in PST when it is 9 AM JST?
On Sunday, September 20, 2026, 9:00 AM JST is 5:00 PM PDT (previous day) in Pacific Time.
How many hours ahead is JST from PST?
It depends on the time of year because of daylight saving time. Now until Nov 1, 2026: Japan Standard Time is 16 hours ahead of Pacific Time (JST → PDT). Nov 1, 2026 – Mar 14, 2027: Japan Standard Time is 17 hours ahead of Pacific Time (JST → PST).
Should I use PST or PDT?
Pacific Time is on PDT (UTC-7) on Saturday, September 19, 2026. Many people write “PST” all year, but strictly PST means Pacific Standard Time (always UTC-8). This converter follows the real local time in Pacific Time, including daylight saving time.

On Saturday, September 19, 2026, good options are 7:00 AM JST (3:00 PM PDT), 8:00 AM JST (4:00 PM PDT), 9:00 AM JST (5:00 PM PDT), 10:00 AM JST (6:00 PM PDT). There is no overlap of 9 AM–5 PM working hours, so these fall early or late for one side.
Does JST change for daylight saving time?
No. JST stays at UTC+9 all year.
Does PST change for daylight saving time?
The region changes: Pacific Time switches between PST and PDT, so conversions depend on the date. PST itself always means UTC-8.
