Date and time notation in Australia

Date and time notation in Australia most commonly records the date using the day-month-year format (14 August 2020), while the ISO 8601 format (2020-08-13) is increasingly used for all-numeric dates. The time can be written using either the 12-hour clock (7:21 pm) or the 24-hour clock (19:21).

Date

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

  • 13 August 2020
  • 2020-08-13 or 13/08/2020

The ISO 8601 date format (2020-08-13) 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 (13/08/20).

Weeks are most identified by the last day of the week, either the Friday in business (e.g., "week ending 19/1") or the Sunday in other use (e.g., "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"). 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. 2020-W33) is not widely understood. Some more traditional calendars instead treat Sunday as the first day of the week.

Time

The Australian government allows writing the time using either the 24-hour clock (19:21), which is commonplace in technical fields such as military, aviation, computing, navigation, and the sciences; or the 12-hour clock (7:21 pm). The before noon/after noon qualifier is usually written as "am" or "pm". A colon is the preferred time separator.[2]
