AWST vs HST: what's the time gap?
HST is 18 hours behind AWST. In everyday terms, once you know the time on one side you just subtract 18 hours to get the other — so a call between Perth and Honolulu is always 18 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 AWST?
And in Australian Western Standard Time (AWST), it’s currently Tuesday, June 30, 2026 · 1:54:05 AM. Compare the two and the 18 hours gap is easy to see.
Planning a meeting across AWST and HST?
For example, a 9:00 AM AWST meeting takes place at 3:00 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 AWST–HST difference?
The labels AWST and HST are fixed offsets, so the result on this page is always exact. Neither side changes its clocks for daylight saving, so the difference you see here is the same in summer and winter.
How accurate is this AWST to HST conversion?
We don’t guess. AWST 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.
