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

AEST to JST

AEST is UTC+10 and JST is UTC+9 today — JST is 1 hour behind AEST. Abbreviations are for reading: this page resolves AEST to Australia/Sydney and JST to Asia/Tokyo, which are the names that do not go ambiguous.

Common questions

What is AEST in JST?

JST is 1 hour behind AEST today: noon in AEST is 11:00 in JST.

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 JST meet?

Working hours overlap for 8 hours a day: the shaded overlap is 09:00–17:00 in JST (10:00–18:00 your time).
