January carries two fixed public holidays: New Year's Day on 1 January and Australia Day on 26 January. 27 January 2027 falls inside the 31-day month that both dates bookend, with school holidays and the Australian Open running through the weeks in between. Where either date lands on a weekend, several states shift the public holiday to the following Monday, the same rule applied to Christmas and Boxing Day later in 2027.
The Ekka public holiday in greater Brisbane is held on a Wednesday during the Royal Queensland Show each August, one of the few recurring public holidays fixed to this day of the week. Wednesday 27 January 2027 falls on the same weekday as this regional observance, which applies only within greater Brisbane and not to the rest of Queensland.
Contracts and legal deadlines that specify calendar days count every day from 27 January 2027 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.
