Michael Jackson takes issue with Michael Pinder for referring to 12 am as
the time when the Sun is overhead (Letters, 2 March, p 51).
As am is short for “ante meridiem” or “before midday” and pm is short for
“post meridiem” or “after midday”, it is just as incorrect to refer to 12
o’clock as pm. It should be described as “12 noon”, and the night-time
counterpart as “12 midnight”.
