Comparing Time Zones: BRT and AWST

BRT runs on Brasilia Time (BRT) at UTC-03:00. AWST runs on Australian Western Standard Time (AWST) at UTC+08:00. That puts BRT 11 hours ahead of AWST — a difference of +11h at the current offsets.

In practice, when it is 9:00 AM in BRT it is 8:00 PM in AWST. Midnight in BRT is 11:00 AM in AWST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert BRT to AWST time

Scheduling a call from BRT to AWST: a 10:00 AM start in BRT lands at 9:00 PM in AWST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +11h gap: BRT and AWST 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 AWST is 8:00 PM in BRT.
Coordinating a BRT-based team with AWST contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a +11h gap is not.
With a +11h gap there is no shared 9-to-5 window, so alternate the early start: one week BRT takes the early slot, the next week AWST does.

About BRT (Brasilia Time)

Brasilia Time (BRT) is the standard time in the most populous regions of Brazil, including São Paulo, Rio de Janeiro, and the capital Brasília. Brazil abolished daylight saving time in 2019, so BRT is now observed year-round in these regions. Brazil spans four time zones in total.

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.

Best time to call between BRT and AWST

With a +11h offset there is no overlap inside a normal 9 AM – 5 PM day. AWST opens at 9:00 AM AWST, which is 8:00 PM in BRT, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

BRT and AWST have no shared working hours because of the +11h gap. Teams need to alternate early starts or rely on asynchronous handovers.

BRT is 11 hours ahead of AWST (BRT UTC-03:00 → AWST UTC+08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
