What's the best time for a JST–PST call?
For example, a 9:00 AM JST meeting takes place at 4:00 PM PST (−1 day). The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the JST–PST difference?
The labels JST and PST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this JST to PST conversion?
We don’t guess. JST and PST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Frequently asked questions
How many hours behind JST is PST?

Do JST or PST use daylight saving time?
Japan Standard Time (JST) is a fixed offset with no daylight saving; Pacific Standard Time (PST) observes daylight saving, alternating with PDT.
Why might the real-world JST–PST difference change during the year?
The labels JST and PST are fixed offsets, so this converter is always exact. But Pacific Standard Time's region switches between standard and summer time, so for part of the year you may actually want JST to PDT. Always check which label a region is currently using before you schedule.
