About JST and PST
Japan Standard Time (JST) is used across Japan, including Tokyo and Osaka. Japan does not observe daylight saving time.
US Pacific Time (PST/PDT) is used in Los Angeles, San Francisco, Seattle, San Diego and Vancouver. Clocks shift to PDT (daylight time) from March to November.
Time difference between JST and PST
PST is 17 hours behind JST in winter (January) and 16 hours behind JST in summer (July), because of daylight saving changes. The clocks and table above are computed live from the official IANA time zone database in your browser, so daylight saving transitions are always already included.
Best hours for meetings
Scan the table for rows where both sides land inside working hours (9:00 to 18:00). Rows where one side is early morning or late evening are workable for a quick call; avoid rows where either side is in the middle of the night. To line up three or more cities at once, use the time zone converter and meeting planner.
