The spring racing carnival runs through October in the lead-up to the Melbourne Cup, held on the first Tuesday of November. 13 October 2028 falls inside this build-up, alongside the NRL and AFL grand finals held earlier in the month, two of the biggest fixtures on the national sporting calendar.
Friday 13 October 2028 is the last working day of the standard Monday-to-Friday week, the fifth and final working day before the weekend begins. A public holiday landing on this day of the week joins directly onto the Saturday and Sunday that follow it, forming a three-day weekend without using any annual leave.
Contracts and legal deadlines that specify calendar days count every day from 13 October 2028 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. The difference between the two conventions can shift a deadline by several days once weekends and holidays are counted.
