Why people convert Hong Kong to Honolulu time

Scheduling a call from Hong Kong to Honolulu: a 10:00 AM start in Hong Kong lands at 4:00 PM in Honolulu the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -18h gap: Hong Kong and Honolulu 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 Honolulu is 3:00 PM in Hong Kong.
Booking travel or deliveries: tracking Honolulu local time against Hong Kong keeps pickup windows and arrival estimates honest across the -18h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM HKT" is unambiguous; "3 PM" across a -18h gap is not.
With a -18h gap there is no shared 9-to-5 window, so alternate the early start: one week Hong Kong takes the early slot, the next week Honolulu does.
