Understanding JST to PST Time Conversion
What is JST (Japan Standard Time)?
Japan Standard Time (JST) is the standard time zone used in Japan. It is 9 hours ahead of Coordinated Universal Time (UTC+9). Japan does not observe Daylight Saving Time, so JST remains constant throughout the year.
What is PST (Pacific Standard Time)?
Pacific Standard Time (PST) is used in parts of North America, including the west coast of the United States and Canada. It is 8 hours behind Coordinated Universal Time (UTC-8). During Daylight Saving Time (usually March to November), the time zone becomes Pacific Daylight Time (PDT), which is UTC-7.
Time Difference Between JST and PST
The time difference between Japan Standard Time (JST) and Pacific Standard Time (PST) is 17 hours. When it's noon in Japan, it's 7:00 PM the previous day in Los Angeles.
During Daylight Saving Time, when Pacific Time becomes PDT, the difference is 16 hours.

Business Hours Overlap
When scheduling meetings between Japan and the Pacific coast of North America, be aware that there is minimal overlap in standard business hours:
Japan business hours (9:00 AM - 5:00 PM JST) = 4:00 PM - 12:00 AM PST (previous day)
Pacific business hours (9:00 AM - 5:00 PM PST) = 2:00 AM - 10:00 AM JST (next day)
The best overlap time is typically early morning in Pacific Time, which corresponds to late afternoon/evening in Japan.
