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. 5 April 2028 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.

Wednesday 5 April 2028 falls on the same weekday as this regional observance, which applies only within greater Brisbane and not to the rest of Queensland.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2028 can show a different total depending on which state's calendar applies to 5 April. Interstate businesses need to check more than one state's list before setting a national deadline.
