What is the proper way to abbreviate the word “month”? Unfortunately, there is no one proper way. It all depends on context:- mth (plural mths) – most popular
mo. (plural mos.).
MM and M are usually used in date formats like MM/DD/YY. In some documents it is common to see just “m”.
Please note: Abbreviations used on this page denote common usage unrelated to documenting sources. When documenting sources using MLA style, the months with four or fewer letters, e.g. May, June, and July are not abbreviated, the remaining months Jan., Feb., Mar., Apr., Aug., Sept., Oct., Nov. and Dec. are abbreviated. When documenting sources using APA style, no abbreviations are used, all months are spelled out in full.
