An essay on the vagueness of 12:00 a.m. and 12:00 p.m. is presented. It outlines the meanings of the abbreviations a.m. and p.m. which refer to before noon (a.m.) for "ante meridiem" and after noon (p.m.) for "post-meridiem". It offers the appropriate language to be used to resolve the ambiguity in 12:00 midnight.
