Why people convert PET to Japan time

Scheduling a call from PET to Japan: a 10:00 AM start in PET lands at 12:00 AM in Japan the next day, so you can confirm the slot without doing the arithmetic yourself.
Handling a +14h gap: PET and Japan 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 Japan is 11:00 PM in PET.
Watching a live event or market open: PET viewers need 11:00 PM in Japan to catch a 9:00 AM start there, and 10:00 AM if the event is anchored to PET.

Always state the zone abbreviation, not just the hour. "3:00 PM PET" is unambiguous; "3 PM" across a +14h gap is not.
With a +14h gap there is no shared 9-to-5 window, so alternate the early start: one week PET takes the early slot, the next week Japan does.
