Understanding the -1h Gap: AKST vs HST
AKST runs on Alaska Standard Time (AKST) at UTC-09:00. HST runs on Hawaii Standard Time (HST) at UTC-10:00. That puts AKST 1 hour behind HST — a difference of -1h at the current offsets.

Why people convert AKST to HST time
- Scheduling a call from AKST to HST: a 10:00 AM start in AKST lands at 9:00 AM in HST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both AKST and HST are inside the 9-to-5 working day between 10:00 AM and 5:00 PM AKST time (9:00 AM–4:00 PM HST). That is roughly 7 hours of usable overlap.
- Watching a live event or market open: AKST viewers need 8:00 AM in HST to catch a 9:00 AM start there, and 1:00 AM if the event is anchored to AKST.
- Always state the zone abbreviation, not just the hour. "3:00 PM AKST" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM AKST as the recurring meeting window if you work primarily from AKST and need HST colleagues present.
About AKST (Alaska Standard Time)
Alaska Standard Time (AKST) is used in nearly all of Alaska. Due to Alaska's vast geographic size, the Aleutian Islands use Hawaii-Aleutian Standard Time instead. During summer months, Alaska switches to Alaska Daylight Time (AKDT, UTC-08:00).
About HST (Hawaii Standard Time)
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.

Both AKST and HST sit inside the 9 AM – 5 PM working day between 10:00 AM–5:00 PM AKST, which is 9:00 AM–4:00 PM HST. That gives roughly 7 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
AKST and HST share 7 hours of working-hours overlap (10:00 AM–5:00 PM AKST), so scheduling a live meeting is straightforward.
AKST is 1 hour behind HST (AKST UTC-09:00 → HST UTC-10:00). The shared working window is 10:00 AM–5:00 PM AKST. Remember to re-check around daylight-saving transitions.
