About aussiecalendar.com.au
A public holiday calendar for Australia that is generated from the rules, checked against official data every month, and maintained by one person who would like to hear when it is wrong.
What this site is
aussiecalendar.com.au lists every Australian public holiday by state and territory for 2025 to 2028, shows them as a list or a calendar, and runs a long weekend planner that works out which days of annual leave buy the longest break. It also has a page for every holiday, a lookup for any calendar date, and plain-language guides to the rules behind the calendar.
The site exists because the official sources are scattered across eight governments, each publishing on its own website in its own format, and none of them answers the question most people actually have: "if I take these three days off, how long am I away?"
Who makes it
The site is built and maintained by Henry Huynh, an independent software developer in Australia. It is a one-person project, not a company, and there is no editorial team behind it. Every date rule, every line of copy and every guide is written and checked by the same person, which is both its limitation and the reason it can be kept accurate: there is nobody to pass the buck to.
It is not affiliated with any government, employer group, union or the Fair Work Ombudsman. Where it cites those bodies, it links to them.
Where the dates come from
The dates are not typed in by hand each year. They are generated from a set of rules, one per holiday per state, that encode what the legislation says: "the second Monday in June", "26 January, or the following Monday if that is a weekend", "the Friday before the last Saturday in September". The rules were written from the state acts and the notices published under them, listed in the guide to how holidays are decided.
Before every build, the generated dates are compared against official government datasets, and a mismatch stops the site from publishing until it is resolved. The datasets used are:
| Source | Publisher | Covers |
|---|---|---|
| Australian Public Holidays Dates dataset | Department of the Prime Minister and Cabinet, via data.gov.au | All states, up to 2025 |
| Victorian Government Important Dates | Victorian Government, via data.vic.gov.au | Victoria, several years ahead |
| ACT Public Holidays and Term Dates | ACT Government, via data.act.gov.au | ACT |
| State government gazettes and holiday pages | VIC, NSW, QLD, SA, WA, TAS, NT, ACT | Hand-checked for dates the datasets do not reach |
Dates the relevant government has not yet confirmed are marked provisional wherever they appear: Grand Final Friday in Victoria until the AFL fixture is locked in, Western Australia's King's Birthday until it is proclaimed, and Queensland's council show holidays until the annual list is gazetted.
How often it is checked
The official datasets are re-fetched and re-verified on the first of every month, and the site is rebuilt at the same time so that countdowns, the year range and newly confirmed dates roll forward. When a government changes a holiday, the rule is updated, a test is added so it cannot silently regress, and the change is noted on the affected pages.
Copy in the guides and holiday pages carries a "last reviewed" date. If a guide describes a rule that has since changed, the contact page is the fastest way to get it fixed.
What it leaves out on purpose
- Local council holidays in New South Wales, Victoria and Western Australia (show half-days, local race days, regional King's Birthday dates). They are declared council by council, and the site would rather list nothing than list something stale. Queensland, NT and Tasmanian regional days are included because they are set at state level.
- School holidays. Different again by state and sector, and well covered by the education departments.
- Penalty rate figures. They depend on the award, so the site explains how they work and points to the Fair Work Ombudsman's calculator rather than publishing numbers that would be wrong for most readers.
- Historical years before the ones listed, beyond what is needed to verify the rules.
Corrections
If a date is wrong, the report form sends the details straight to the maintainer, and the report is checked against the gazette before anything is changed. Confirmed errors are fixed in the next build, usually within a day or two. The same form handles missing holidays, holidays that should not be listed, and planner results that look off.
