pm or p.m.

According to the University of Oxford Style Guide (page 3) in the following document https://www.ox.ac.uk/sites/files/oxford/media_wysiwyg/University of Oxford Style Guide.pdf, the term "p.m." shall be written as "pm", while on the Oxford Dictionaries website it is written as "p.m.". Which version is correct?

  • Hi there @denbi90.

    This is house style for us. It's more traditional to give lower-case abbreviations with points after each letter, though increasingly they are written with no points. Using pm is not wrong, it’s just a style choice.

    I hope this helps.
