How many hours apart are PST and JST?
JST is 17 hours ahead of PST. In everyday terms, once you know the time on one side you just add 17 hours to get the other — so a call between Los Angeles and Tokyo is always 17 hours apart.
What's the current time in JST?
Right now the time in Japan Standard Time (JST) is Tuesday, June 30, 2026 · 2:53:56 AM. It ticks every second, so you’re always looking at the live JST clock.
And what time is it in PST?
And in Pacific Standard Time (PST), it’s currently Monday, June 29, 2026 · 9:53:56 AM. Compare the two and the 17 hours gap is easy to see.
What's the best time for a PST–JST call?
For example, a 9:00 AM PST meeting takes place at 2:00 AM JST (+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 PST–JST difference?
The labels PST and JST 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 PST to JST conversion?
We don’t guess. PST and JST 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 ahead of PST is JST?

Do PST or JST use daylight saving time?
Pacific Standard Time (PST) observes daylight saving, alternating with PDT; Japan Standard Time (JST) is a fixed offset with no daylight saving.
Why might the real-world PST–JST difference change during the year?
The labels PST and JST 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 PDT to JST. Always check which label a region is currently using before you schedule.
