Why people convert PDT to Tokyo time
- Scheduling a call from PDT to Tokyo: a 10:00 AM start in PDT lands at 2:00 AM in Tokyo the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +16h gap: PDT and Tokyo 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 Tokyo is 1:00 AM in PDT.
- Coordinating a PDT-based team with Tokyo contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM PDT" 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 PDT takes the early slot, the next week Tokyo does.
