Why people convert HKT to PDT time
- Scheduling a call from HKT to PDT: a 10:00 AM start in HKT lands at 7:00 PM in PDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -15h gap: HKT 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 6:00 PM in HKT.
- Watching a live event or market open: HKT viewers need 6:00 PM in PDT to catch a 9:00 AM start there, and 3:00 PM if the event is anchored to HKT.
- Always state the zone abbreviation, not just the hour. "3:00 PM HKT" is unambiguous; "3 PM" across a -15h gap is not.
- With a -15h gap there is no shared 9-to-5 window, so alternate the early start: one week HKT takes the early slot, the next week PDT does.
