AEST to HST Converter
This page converts Australian Eastern Standard Time (AEST) to Hawaii Standard Time (HST). HST is 20 hours behind AEST, so a meeting at one time slides predictably to the other. Edit the time or date to begin.
Daylight saving notes
In southern Australia, daylight saving time runs from the first Sunday in October to the first Sunday in April. That affects Australian Eastern Standard Time (AEST).
AEST to HST conversion chart
For example, a 9:00 AM AEST meeting takes place at 1:00 PM HST (−1 day). Concretely, when Sydney (AEST) and Honolulu (HST) set up a call, hST is 20 hours behind AEST.

- Need a different day? Click the date field and the result follows, rolling over if it crosses midnight.
AEST vs HST: what's the time gap?
HST is 20 hours behind AEST. In everyday terms, once you know the time on one side you just subtract 20 hours to get the other — so a call between Sydney and Honolulu is always 20 hours apart.
What's the current time in HST?
Right now the time in Hawaii Standard Time (HST) is Monday, June 29, 2026 · 7:54:05 AM. It ticks every second, so you’re always looking at the live HST clock.
And what time is it in AEST?
And in Australian Eastern Standard Time (AEST), it’s currently Tuesday, June 30, 2026 · 3:54:05 AM. Compare the two and the 20 hours gap is easy to see.
When is a good time to schedule a AEST to HST meeting?
For example, a 9:00 AM AEST meeting takes place at 1:00 PM HST (−1 day). The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
Does daylight saving time change the AEST–HST difference?
The labels AEST and HST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
How accurate is this AEST to HST conversion?
We don’t guess. AEST and HST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.

Frequently asked questions
How many hours behind AEST is HST?
HST is 20 hours behind AEST — a fixed 20 hours difference, since both are fixed-offset labels.
What time is it in HST when it's 12:00 PM AEST?
When it's 12:00 PM (noon) AEST, it's 4:00 PM HST the previous day.
Do AEST or HST use daylight saving time?
Australian Eastern Standard Time (AEST) observes daylight saving, alternating with AEDT; Hawaii Standard Time (HST) is a fixed offset with no daylight saving.
Why might the real-world AEST–HST difference change during the year?
The labels AEST and HST are fixed offsets, so this converter is always exact. But Australian Eastern Standard Time's region switches between standard and summer time, so for part of the year you may actually want AEDT to HST. Always check which label a region is currently using before you schedule.
