Date Format: Day Month Year

Day–month–year is a legitimate human-readable date order used by some regional and institutional styles. The Australian Government Style Manual uses forms such as “22 July 2024,” while Microsoft’s house style uses month–day–year; choose the convention that matches your audience and style guide.

Quick answer

Day–month–year is valid where your locale or house style calls for it, for example “22 July 2024.” It is not a universal English date order.

Important caveats

Contrast Boundary

Other house styles differ; Microsoft, for example, specifies month–day–year. Do not present either order as universal English grammar.

Regional Style

The Australian Government Style Manual uses day–month–year in body text and recommends consistency.

Month Day Year Date Format

Month–day–year is a common human-readable date order and Microsoft’s house style uses forms such as “July 31, 2016.” Other regional guides use different orders, so the correct choice depends on audience, locale, and governing style.
