Holidays

Australia Public Holidays Calculator

Australia's nationally-observed public holidays for any year, calculated live from the actual rules.

Year

Why "national" only covers so much

Australia's public holidays are set state by state, not nationally, and only a handful are consistent across every state and territory. The King's Birthday, for instance, is observed on different Mondays in different states (and not at all in Western Australia and Queensland, which pick their own date entirely); Labour Day moves around by months depending on the state. This calculator shows the holidays that are common to essentially all states — for a specific state's exact calendar, check that state government's site directly.
