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. 15 April 2029 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 15 April 2029 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.
2029 has 365 days on the calendar. Leap years add a single extra day to February, giving those years 366 days instead of 365 and shifting the day-of-year number for every date from March onward by one compared with an ordinary year. This is the only irregularity in the length of the Australian calendar year.
