Month Abbreviations
12 abbreviations · part of Units of Measurement Abbreviations
Standard abbreviations for the months of the Gregorian calendar, as used in calendars, tables, document dates and data formats. The three-letter forms (Jan, Feb, Mar and so on) appear on calendars and in software, while AP style abbreviates only Jan., Feb., Aug., Sept., Oct., Nov. and Dec., and only with a specific date; March, April, May, June and July are always spelled out. May has no abbreviation because its name is already three letters long.
