In response to comments on the 12 noon / 12 midnight question:
If
	a.m. = ante meridiem (before the middle of the day)
	p.m. = post meridiem (after the middle of the day),

then 12:00 m is noon since 
	m = meridiem (the middle of the day)

All's well so far.

Now what happens if one is a navigator or astrologer, and has
ephemerides calculated for UMT noon and midnight.  (It's pretty
important to know which is which, or you will wind up in some
pretty strange places.)  How do you designate them?

I have both noon and midnight ephemerides, and I use N (noon)
and M (midnight), because of the analogy with English words.
I don't know the Latin for midnight, but it's probably something
like "merinoctum", which also begins with an "m" and is no help.

If there are other practical designations for this, I would like
to know.
