From https://en.wikipedia.org/wiki/King%27s_Official_Birthday : "As Western Australia celebrates Western Australia Day (formerly known as Foundation Day) on the first Monday in June, the governor of Western Australia each year proclaims the day on which the state will observe the King's Birthday, based on school terms and the Perth Royal Show.[1] There is no firm rule to determine this date, though it is usually the last Monday of September or the first Monday of October."

@mleech Are you interested in maintaining the annual announcements here? Otherwise, the date will not be right for the next few years.
