ANZAC Day dawn services are held nationwide on 25 April, and Easter's four-day break sits within or close to April depending on the year. 18 April 2030 falls in the same 30-day month as both observances, giving autumn the busiest run of national holidays anywhere on the calendar, ahead of the quieter months that follow in May and June.
Thursday 18 April 2030 is a common day for bill payments, invoice due dates and payroll runs across Australian businesses, sitting close enough to the end of the working week to clear outstanding tasks before Friday arrives. Many payroll cycles are timed to land on this day of the week specifically, so that funds clear ahead of the weekend.
2030 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.
