AUTO follows the operating system. Working hours drive the green banding on every grid. All four persist on this device only.

AEST to BRT

AEST is UTC+10 and BRT is UTC−3 today — BRT is 13 hours behind AEST. Abbreviations are for reading: this page resolves AEST to Australia/Sydney and BRT to America/Sao_Paulo, which are the names that do not go ambiguous.

BRT: Brasília time, which tzdata now writes as −03.

Common questions

What is AEST in BRT?

BRT is 13 hours behind AEST today: noon in AEST is 23:00 in BRT.

Is AEST the same all year?

AEST refers to the offset used by Australia/Sydney. Where that zone observes daylight saving, the letters change with it, which is why this site stores the identifier and not the abbreviation.

When can AEST and BRT meet?

They do not overlap during working hours. 06:00–07:00 your time (17:00 there) is the cheapest compromise.
