Wednesday 9 September 2026 falls on the same weekday as this regional observance, which applies only within greater Brisbane and not to the rest of Queensland.
Contracts and legal deadlines that specify calendar days count every day from 9 September 2026 including weekends and public holidays, while deadlines specified in working or business days count only the days this page includes in its working-day total.
