ANZAC Day falls on the fixed date of 25 April, marked nationwide with dawn services regardless of which day of the week it lands on. 23 April 2028 falls inside the same 30-day month, alongside Easter, which moves from year to year but falls within or close to April in most years across the Australian calendar.
Any deadline or bill payment due on Sunday 23 April 2028 moves to the following Monday under standard business-day rules, since Sunday sits outside the working week this page counts by default. This convention applies consistently across contracts, invoices and statutory deadlines throughout Australia, regardless of which state or territory is involved.
The week number shown for 23 April 2028 counts full weeks from the start of 2028, a figure used in payroll cycles, rostering and any planning done in weekly or fortnightly blocks rather than by calendar month. Businesses running fortnightly pay runs rely on this figure to track which of the two alternating pay weeks a date falls in.
