About AWST
A fixed, year-round offset.

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].
- Does AWST ever switch to daylight saving time?
- No; Western Australia currently uses AWST all year, keeping UTC+08:00 without any seasonal shifts.
- Why did Western Australia try DST in the past?
- Western Australia trialed daylight saving several times in the 20th and 21st centuries but rejected it permanently due to public opposition and lifestyle impacts—such as later sunrises in winter.
- How many time zones touch AWST?
- AWST sits next to Australian Central Standard Time (UTC+09:30) to the east and aligns neatly with Singapore, Malaysian Standard Time, and China Standard Time (UTC+08:00).
- What is the ideal overlap for calling Perth from Europe?
- Because AWST is UTC+08:00 with no DST changes, European morning slots (roughly 8–10 a.m. CET) correspond to late afternoon in Perth—making mid-morning EU calls land neatly before Perth’s end of business.
- Why does Perth not share a wall-clock time with Sydney except briefly?
- Sydney observes daylight saving (UTC+11:00 in summer) while Perth stays at UTC+08:00; they only overlap during spring and autumn transitions if you ignore DST—but not broadly in practice—keeping their clocks apart most of the year.
- Is AWST used uniformly across all of Western Australia?
- Yes—Perth and the entire state use AWST; unlike the eastern states, WA has never split its time zone by region or DST adoption.
- When did Western Australia latest trial DST?
- The most recent trial was from 2006 to 2009; public feedback and voted referenda afterward confirmed no permanent shift, so AWST remains fixed.
- How does AWST align with neighboring Asian markets?
- AWST shares its UTC+08:00 offset with Singapore, Hong Kong, and China Standard Time—making it easy to sync with major Asian business hubs without seasonal clock adjustments.
