What is King's Birthday?
Western Australia's King's Birthday is a WA public holiday with a state-specific annual date. It is separate from the dates used by Queensland and the six-jurisdiction group.
The WA Government is the source for the displayed date. The annual value must be retained because this is not a single Australia-wide observance.
Keeping the WA key separate also allows the state's own public-holiday page to be linked as the direct provenance source.
