AWST and UTC on the World Map
The map below highlights the AWST (Australian Western Standard Time) and UTC (Coordinated Universal Time) timezone regions across the globe.
AWST – Australian Western Standard Time
UTC+08:00Australian Western Standard Time (AWST) is the time zone for Western Australia, 8 hours ahead of UTC.
- •Western Australia does not observe daylight saving time.
- •Perth is the most isolated major city in the world.
- •AWST is the same offset as China Standard Time and Singapore Time.
UTC – Coordinated Universal Time
UTC+00:00Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.
- •UTC is the basis for all civil time zones worldwide.
- •The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
- •UTC is based on atomic clocks and is accurate to within a nanosecond per day.
- •Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
- •Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.
Comparing Time Zones: AWST and UTC
AWST runs on Australian Western Standard Time (AWST) at UTC+08:00. UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. That puts AWST 8 hours behind UTC — a difference of -8h at the current offsets.
In practice, when it is 9:00 AM in AWST it is 1:00 AM in UTC. Midnight in AWST is 4:00 PM in UTC. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert AWST to UTC time
- Scheduling a call from AWST to UTC: a 10:00 AM start in AWST lands at 2:00 AM in UTC, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -8h gap: AWST and UTC have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in UTC is 1:00 AM in AWST.
- Booking travel or deliveries: tracking UTC local time against AWST keeps pickup windows and arrival estimates honest across the -8h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM AWST" is unambiguous; "3 PM" across a -8h gap is not.
- With a -8h gap there is no shared 9-to-5 window, so alternate the early start: one week AWST takes the early slot, the next week UTC does.
About AWST (Australian Western Standard Time)
Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.
About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
Best time to call between AWST and UTC
With a -8h offset there is no overlap inside a normal 9 AM – 5 PM day. UTC opens at 9:00 AM UTC, which is 1:00 AM in AWST, so real-time calls need an early-morning or late-evening slot on one side.
Business hours overlap
AWST and UTC have no shared working hours because of the -8h gap. Teams need to alternate early starts or rely on asynchronous handovers.
AWST is 8 hours behind UTC (AWST UTC+08:00 → UTC UTC+00:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
