About AWST
A fixed, year-round offset.
Australian Western Standard Time (AWST) keeps things beautifully simple — it's the steady, unchanging heartbeat of Perth and Western Australia, running on UTC+8 all year round. Whether you're coordinating across oceans or catching the last sunset from Cottesloe, AWST means no daylight saving surprises, just reliable timing that makes scheduling a breeze no matter the season.
IANA zones · the technical identifiers
The zone that resolve to AWST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about AWST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Which parts of Australia use AWST?
- AWST is used by Western Australia, with Perth as its main representative city. The entire region follows a single timezone code with no daylight saving adjustments.
- Does AWST observe daylight saving time?
- No. AWST does not observe daylight saving time — the offset stays fixed at UTC+08:00 throughout the year, simplifying planning across the region.
- What makes AWST unique among global timezones?
- AWST covers a vast area that spans multiple climatic zones, yet follows a single, consistent UTC+8:00 offset. Its stability stands in contrast to many other Australian regions that adjust for DST.
- How many member zones are in the AWST region?
- AWST is represented by one primary zone: Australia/Perth, which covers the entire state of Western Australia.
- Are there any upcoming transitions for AWST?
- No transitions are currently scheduled. The AWST offset has been continuously valid since 29 March 2009, reflecting Western Australia’s decision not to adopt DST.
- How does AWST affect international collaboration?
- AWST's fixed offset makes it easier to coordinate with partners in Asia-Pacific regions, with fewer scheduling surprises compared to zones that shift twice a year.
- Is AWST the same as Western Australia’s historical timezone?
- AWST has been fixed at UTC+08:00 since 2009, when Western Australia stopped observing daylight saving, streamlining timekeeping across the region.
- How does AWST interact with Australian Eastern Time?
- AWST is always two hours behind Australian Eastern Standard Time (AEST), making cross-continental meetings predictable, though eastern states may shift during their DST periods.
- What countries are part of the AWST region?
- Only Australia, specifically Western Australia, uses AWST, with Perth serving as the representative city for this timezone.
