Why people convert Honolulu to MSK time

Scheduling a call from Honolulu to MSK: a 10:00 AM start in Honolulu lands at 11:00 PM in MSK, so you can confirm the slot without doing the arithmetic yourself.
Handling a +13h gap: Honolulu and MSK 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 MSK is 10:00 PM in Honolulu.
Booking travel or deliveries: tracking MSK local time against Honolulu keeps pickup windows and arrival estimates honest across the +13h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM HST" is unambiguous; "3 PM" across a +13h gap is not.
With a +13h gap there is no shared 9-to-5 window, so alternate the early start: one week Honolulu takes the early slot, the next week MSK does.
