Last updated Apr 22, 2026. Representative zones, offset ranges, and city usage are refreshed from the current timezone dataset so abbreviation pages stay tied to real zones instead of static boilerplate.
LHST is used in this dataset for Lord Howe Time. Right now it maps to 1 meaning, 1 IANA zone, and 1 country.
This page uses Australia/Lord_Howe as the live reference, currently at +10:30 (GMT+10:30). That keeps the clock grounded in IANA data even when the abbreviation is more of a standard label than a city-based timezone.
LHST is currently anchored to +10:30, but the listed zone family does use seasonal clock changes. The exact offset can shift when local daylight-saving rules take effect, so long-range scheduling is still safest with the underlying zone name.

LHST currently covers 1 zones across 1 country-level groupings in the dataset. The leading city references include reference-only timezone clusters, which is why this page can say something concrete about where the abbreviation shows up in real schedules.
At the country level, the strongest current usage clusters include Australia. That matters because abbreviations with broad political or regional spread are much easier to misread unless the page makes the country context explicit.

Australia sits in Oceania, specifically Australia and New Zealand, with a current population of 27,536,874 and an area of 7,692,024 km². The capital and major policy anchor is Canberra, which gives the abbreviation a real administrative center instead of a floating offset.
The strongest civic markers behind LHST here are English and AUD (Australian dollar, $). Those details matter because abbreviations show up in airline itineraries, payroll systems, and travel notices that are really describing life in a specific country or territory.
Australia adds the broader geographic backdrop for LHST: Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It has a land area of 7,688,287 km2 (2,968,464 sq mi), making it the sixth-largest country in the world. Australia is the world's flattest and driest inhabited continent. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates including deserts in the interior and tropical rainforests along the coast.
Dryococelus gives the closest encyclopedic description available for this abbreviation family: Dryococelus australis, also known as the Lord Howe Island stick insect, Lord Howe Island phasmid or, locally, as the tree lobster, is a species of stick insect that lives in the Lord Howe Island Group. It is the only member of the monotypic genus Dryococelus. Thought to be extinct by 1920, it was rediscovered in 2001. Although it had been extirpated from Lord Howe itself, a remnant population of 24 individuals was rediscovered on the sea stack of Ball's Pyramid. The species has been called "the rarest insect in the world".

LHST is not heavily split in the current catalog, but the short label still hides the underlying IANA zone and any future policy changes.
Australia/Lord_Howe has an upcoming offset change on October 4, 2026, so the abbreviation can point to a different UTC offset later in the year.
For precise work, the safest equivalent is the exact IANA zone used by your city or system, not the abbreviation by itself.
