Why people convert Honolulu to BST time
- Scheduling a call from Honolulu to BST: a 10:00 AM start in Honolulu lands at 9:00 PM in BST, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +11h gap: Honolulu and BST 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 BST is 8:00 PM in Honolulu.
- Coordinating a Honolulu-based team with BST 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 HST" is unambiguous; "3 PM" across a +11h gap is not.
- With a +11h gap there is no shared 9-to-5 window, so alternate the early start: one week Honolulu takes the early slot, the next week BST does.

Hawaii Standard Time (HST) is used in the state of Hawaii and does not observe daylight saving time. This makes HST one of the most consistent time zones in the US. The Hawaiian Islands are among the last places on Earth to see a new calendar day.
About BST (British Summer Time)

BST is also used to abbreviate Bangladesh Standard Time (UTC+06:00), which is listed separately on this site.
