Usage notes

 * As seen in the quotes above, "12 a.m." has sometimes been used to mean either noon or midnight. However, the National Institute of Standards and Technology contends that those uses are incorrect.
 * Some argue that it should not be used in English as a noun meaning "morning" on account of the fact that it is an abbreviation for a Latin adverbial phrase.
