Why people convert Tokyo to PDT time
- Scheduling a call from Tokyo to PDT: a 10:00 AM start in Tokyo lands at 6:00 PM in PDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -16h gap: Tokyo and PDT 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 PDT is 5:00 PM in Tokyo.
- Keeping family and friends in sync: knowing that 8:00 PM in Tokyo is 4:00 AM in PDT makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM JST" is unambiguous; "3 PM" across a -16h gap is not.
- With a -16h gap there is no shared 9-to-5 window, so alternate the early start: one week Tokyo takes the early slot, the next week PDT does.
