Why people convert Japan to PST time
- Scheduling a call from Japan to PST: a 10:00 AM start in Japan lands at 5:00 PM in PST the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -17h gap: Japan and PST have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PST is 4:00 PM in Japan.
- Watching a live event or market open: Japan viewers need 4:00 PM in PST to catch a 9:00 AM start there, and 5:00 PM if the event is anchored to Japan.
- Always state the zone abbreviation, not just the hour. "3:00 PM JST" is unambiguous; "3 PM" across a -17h gap is not.
- With a -17h gap there is no shared 9-to-5 window, so alternate the early start: one week Japan takes the early slot, the next week PST does.
