Date and time notation in Australia largely follows conventions from British English, like many other aspects of Australian English. It most commonly records the date using the day-month-year format (23 August 2019), while the ISO 8601 format (2019-08-23) is increasingly used for all-numeric dates. The time can be written using either the 24-hour clock (14:41) or 12-hour clock (2:41 pm).

Date[edit]

Australians typically write the date with the day leading, as in the United Kingdom and New Zealand:

  • 23 August 2019
  • 2019-08-23 or 23/08/2019

The ISO 8601 date format (2019-08-23) is the recommended short date format for government publications.[1] The first two digits of the year are often omitted in everyday use and on forms (23/08/19).

Weeks are most identified by the last day of the week, either the Friday in business (e.g., "week ending 19/1") or the Saturday or Sunday in use (e.g., "week ending 20/1" or "week ending 21/1"). Week ending is often abbreviated to "W/E" or "W.E." The first day of the week or the day of an event are sometimes referred to (e.g., "week of 15/1" or "week of 14/1"). Week numbers (as in "the third week of 2007") are not often used, but may appear in some business diaries in numeral-only form (e.g., "3" at the top or bottom of the page). ISO 8601 week notation (e.g. 2019-W34) is not widely understood.[citation needed]

Time[edit]

The Australian government allows writing the time using either the 24-hour clock (14:41), which is commonplace in technical fields such as aviation, computing, navigation, and the sciences; or the 12-hour clock (2:41 pm). The before noon/after noon qualifier is usually written as "am" or "pm". A colon is the preferred time separator.[2]
