Stay up to date with revisions and additions to the Style Manual.
May to July 2024
Dashes: new heading ‘Follow exceptions to the general rule’. Includes new text and examples for en dashes to ensure consistency with the recent update to Dates and time.
February to April 2024
Major revision
‘Dates and time’ has a new structure, revised guidance, new content and updated examples.
To ensure the Changelog is readable, we list major changes only. Minor changes have been logged internally.
Rule changes
- Shortened forms for months and days of the week – We allow more contractions for use as standard abbreviations: ‘Tue’ ‘Thur’ ‘Thu’ ‘Jun’ ‘Jul’ ‘Sep’.
World wars – The amended rule replaces the distinction between Australian and American styles with 2 acceptable styles: ‘First World War’ and ‘World War I’. Our recommendation to use roman numerals is based on corpus evidence, but we acknowledge the use of ‘1’ and ‘2’ by some agencies.
There is a rule change for the shortened form. We now recommend using roman numerals not arabic numerals – write ‘WWII’ not ‘WW2’.
Centuries – Write all centuries with numerals (3rd century). Under the previous rule, both words (third century) or numerals (3rd century) were acceptable style. Evidence supporting the change came from expert advice and corpus data.
We have added an exception for centuries to the relevant rule on the ‘Ordinal numbers’ page.
- Time zones – The initialisms for time zones now appear after the time (13:45 AEST) not before the time (AEST 13:45).
