What is the correct way of stating noon? Is it 12 a.m. or 12 p.m. or
neither?

Thanks,

Noon is 12 p.m. Midnight is 12 a.m. (at least according to my VCR)
This is why we say 12:30 p.m. is afternoon.

"The" correct way? "Noon", "Midday", "12 noon", "12:00" [by the 24hour
clock], etc., would all be correct ways of stating it.

> Is it 12 a.m. or 12 p.m.

No. 12:00 is neither before nor after noon.

It has always been my understanding that a.m. stands for ante
meridian (before midday) and p.m. stands for post meridian (after midday).
Therefore noon should be 12:00 m. (at midday). The logical conclusion is
that 12:00 p.m. indicates midnight -- 12 hours after midday. (Perhaps
12:00 a.m. also indicates midnight -- 12 hours before midday?)

Neither. Noon is 12 M.

Think about it. AM is "ante meridiem" - before noon. PM is "post
meridiem" - after noon. Noon, then, is M. It's not uncommon to find this
usage in nineteenth century texts.

For the last century, though, people have been showing up twelve hours late
for appointments made at 12 M. These are, for the most part, the same
people who pour inflammable liquids on a fire in an attempt to extinguish
it. So modern usage generates the question you asked, and the correct
answer is still unclear.

I strongly prefer to use "Noon" for noon. It's the same number of
characters as "12 AM" or "12 PM" (without the space) and it has the
advantage of being unambiguous.

a.m. stands for 'ante meridiem', 'before noon'.
p.m. stands for 'post meridiem', 'after noon'.

So obviously noon is neither a.m. nor p.m. Unfortunately, that doesn't
stop ignorant people from using '12:00 a.m.' or '12:00 p.m.' to mean noon,
although either one could conceivably be construed to mean midnight.

I haven't seen that usage. Unless I were alerted to pay careful
attention I would automatically assume that "12 M." means "12 midnight".

This whole topic is a non-problem, except in one special
circumstance. I don't think any sensible person would say "12 a.m." or
"12 p.m." and expect to be certainly understood. I think most people
say "noon" and "midnight", although some might use the redundant "12
noon" and "12 midnight".

The one special case where the problem must be faced is in
programming a VCR. If I want to program something to end at midnight,
the machine insists that I say whether I mean a.m. or p.m., and it won't
budge till I make up my mind. If I give the wrong answer the machine
will try to record for 12 hours more than I intend, probably writing
over things on the tape I wanted to save.

To be on the safe side, guarding against the possibility that I
only think I remember which is which, I enter "12:01 a.m.". (This also
provides tolerance for the VCR clock not being set to precisely the
correct time of day.)

If logic governed, we might have a system in which noon could be
either 12:00 a.m. or 00:00 p.m. and midnight could be either 12:00 p.m.
or 00:00 a.m.. Then three minutes past midnight would be nothing but
00:03 a.m., and three minutes past noon would be 00:03 p.m..

12 Noon is 12 p.m. and 12 Midnight is 12 a.m.

But, as you can see you are getting conflicting thoughts on this matter.

I'm another one who invariably says "meridian" ... even though the word,
in all strictitude, should be "meridiem."

In general usage (I'm not saying it makes sense, mind you) 12 a.m. is
midnight, and 12 p.m. is noon. My watch switches over to p.m. at noon,
in any case.

There is a long history of indicating this by saying

12 N for noon

12 M for midnight.

I can't remember when or where I learned this, but I believe it was in ham
radio transmissions.

It's redundant only if you interpret noon to mean 12 o'clock on the dot.
"I always eat at noon" can hardly mean that. Or "midnight snack" for that
matter. There are other phrases that similarly nail down the time: "They
shot it out at high noon"; "The witches gathered on the stroke of midnight."

If you see the "12 o'clock" times referred to in a newspaper that uses
AP style, they will be called "noon" and "midnight."

Excellent point. In normal, everyday speech, there is no problem.
Everyone says "noon" or "midnight", if necesary, to avoid ambiguity.
The problem arises when you are forced to interact with a stupid
computer program, like the one in a VCR ; and that may well have been
the original poster's problem.
The problem is a bit more common than just VCRs, though. For instance,
the appointment editor that I am occasionally forced to use (there are
more reasons why I hate the thing), thinks in a.m. and p.m., and when I
want to schedule a meeting from 11 to 12, I have to think hard which of
the two options on the menu I have to pick for the end time.

Of course, in the real world, we use a 24-hour clock, and we regard the
use of a.m. and p.m. in computer programs as being on the same level of
cultural progress as shillings, pence, miles, gallons, furlongs, chains,
gills, donkey traffic, witch doctors, child marriage, and banknotes all
of the same size and color. Luckily, the better operating systems now
provide a 24-hour clock by default.

[snipped: observations that noon is neither am nor pm, but that VCRs, for
example, insist on the choice of one or the other.]

I've found a simple & logical way to remember what the VCR wants, and
generally avoid confusing myself about 12 am vs 12 pm.

Consider that a minute after noon is indisputably 12:01 pm, and for that
matter a second after would be 12:00:01 pm. It makes best sense to let
12:00:00 have the same am/pm sense as the rest of the 12:xx:xx hour, so
make noon 12 pm.

Still, when circumstances permit, I'd certainly prefer "12 noon", or just
"noon", to "12 pm". And yes, a 24-hour clock is nicely unambiguous.

Bus, train, etc. schedules use 12:00 p.m. to mean noontime.

Many students (young persons acquiring a literary consciousness) write
"12:00 a.m." or "12:00 p.m." without knowing about the meridian. When
questioned, invariably they translate "a.m." as "after morning" and "p.m."
as "I dunno." Go figure.

Furthermore, custom accounts the instant of midnight as the first instant of
a new 24-hour day, rather than as the last of an old. Thus, midnight really
is _ante meridiem_. Since midnight is 12 a.m., we might as well call
noon 12 p.m.

>What is the correct way of stating noon? Is it 12 a.m. or 12 p.m. or

I've seen various answers stating and explaining that it is neither.
However in practice the term "noon" usually refers to an approximate
time. If you really wanted to refer to 12:00:00.0000000000000... then
"noon" would be the most concise way of saying it. Otherwise (and
usually), "p.m." is conventional, and consistent with other times
starting "12".

Next question. When is "midnight on Tuesday"?

Logical. Still, ambiguous enought that most legal situations, like
executions, specify 12:01 AM to indicate the start of the day, clearly not
trusting 12:00 AM/PM.

Cases of mistribution (by the way, shouldn't that be
"misattrition"?) are common in Usenet, but this case is different.
Usually when someone complains about being misquoted, a count of ">"s
shows that he or she was not. In this case, however, the count shows
that Daan Sandee is clearly quoted as asking the questions.

Tracing back though the thread, though, it turns out that
Christopher Monsour was not the culprit. He quoted what he found in
Jonathan Lundell's posting, and it was in Jonathan Lundell's posting
that the misattribution originally occurred.

The message to which Jonathan Lundell responded was from Daan
Sandee, and it had:

I did not know how fortunate we really are living in the Real
World(tm) until I stumbled over these fossil remains in MS Windows
NT...

In the Print Manager of that OS there is a selection for the operating
(or availability) hours for a printer, and it's in a.m. - p.m.
notation.

I finally figured out the oddest thing about the 12 hour clock -- you
_do_not_ reset the counter at noon or at midnight. The system would
be logical if those were the two reset moments, start with 00:01 after
12:00, but no, you go to 12:59 _and_ then jump to 1:00. Oh Bog!

I'm still not sure when our printers will operate...

Generalizing from my own case to the entire English-speaking world (a
time-honored custom in a.u.e), it would ordinarily be taken to be the end
of Tuesday; that is, "midnight on Tuesday" is part of "Tuesday night"
rather than "Wednesday morning" or "Tuesday morning". [I here acknowledge
that "midnight" may be interpreted as the timeless boundary between two
days. Pooh.]

The use of midnight to separate days is, of course arbitrary, though not so
arbitrary as midnight 31 Dec to separate years.

I have seen the same concept being used in legal contracts such as an
insurance policy which becomes effective at 12:01 am of the specified day.
In face, I've heard a story about an insurance company losing a legal
battle simply because of the fact that the contract specified 12:00 am and
experts in the matter testified that such a point in time does not exist!
In normal writing, I either simply use "noon" or "midnight" or write
12:00 without an am/pm designation.

Going back to the orginal question....the correct way of stating (i.e.
writing) 12:00 noon is neither a.m. nor p.m. It is just m. (or M) because
noon is the meridian.

I'd go farther than this. 4 o'clock Wednesday morning is *also*
Tuesday night. Wednesday morning doesn't start until you've slept,
gotten up, had a shower and a coffee.

Depends on the context. If one is working the `swing shift' from four to
midnight, then midnight is the end of Tuesday. This might be written as
"4:00 p.m. to 12:00 p.m." or shortened to "4-12 p.m. The next shift will be
Wednesday's early shift which will work from midnight to eight.

A party might be said to begin at eight o'clock and last until midnight.
If I say that an event is expected to occur between eleven and twelve p. m.
Tuesday night I mean, of course during the final hour of the day. On the
other hand, if I were to say that I heard a noise during the night sometime
after midnight, I mean since the beginning of the day.

If something is scheduled to go into effect at midnight on Tuesday, the
begining of Tuesday is probably what is meant and could be written as 12
a.m., Tuesday. To avoid confusion it might be best to write something like
"midnight, Sept. 16/17, 1996".

All of this is handled neatly when 24 hour time is used. In the military
the first watch of the day is from 0000 to 0400 (midnight to 4 a.m.) and
the last watch is from 2000 to 2400 (8 p.m. to midnight).

Unfortunately this form of reasoning, logical though it is, fails to chime
with established usage, since otherwise "10:15 am" would indicate what is
commonly referred to as "1:45 am".

It seems sensible to let 12pm be one minute before 12:01pm, and it also seems
sensible for 12:01pm to be one minute after noon, provided we consider "am"
and "pm" as dividing the 24-hour day into two halves separated by the moments
of noon and midnight. It would make much more sense, of course, if we were
to think of 12 as meaning 0.

Almost all US air carriers use A.M./P.M. for their schedules (United being
the lone exception that I'm aware of). Schedules using the 24-hour clock
are fairly standard for airlines outside the US. I think the same apply
to trains and buses.

Inasmuch as TV Guide (the most widely circulated magazine in the country)
uses a 12-hour clock, it would be foolhardy for a VCR manufacturer to
produce a programmable interface that did not offer a 12-hour clock. Do
you think Americans would sit still for having to add 12 to the number in
the TV Guide to program their VCRs?

I dispute your "indisputably". To me 12:01 pm does not mean "12 hours
and one minute post meridiem", it means "the 12:01 that's post
meridiem", as opposed to the other "12:01" that's ante meridiem.

I see nothing illogical about am/pm. It's inconvenient in the digital
age, but not illogical.

Yes, and damn easy to screw up on that account, thank you very much. But
then there's the popular "VCR+" system, in which each broadcast's listing
includes an obscurely-generated numerical code that, when programmed into
the VCR, generates the data needed to record the proper channel between
the proper times.

I agree with Martin.
12 midnight should be written as 0.00 am.
12 noon should be written as 0.00 pm.
In the twelve-hour system there is no such thing as 12.01 am (or pm).

Not according to my Webster - the second def is the line you mention.
meridian's first def is actually archaic for the hour of noon.

And if you know that, then no, 12:00 m. is not confused with midnight. In
all my considerable years as clerk/typist/secretary/assistant, I have
never had anyone show up at midnight when I wrote "... will begin at
12:00 m."

But the whole point is: 12:00 m. is the correct way to write 12:00 noon.

But not logical enough. As it has been abundantly
pointed out in this thread, both 12 AM and 12 PM are so
ambiguous as to be dangerously useless. And with good
reason: noon and midnight are neither ante nor post, but
are the infinitesimal dividers of ante and post.
I suggest that noon and midnight have their owm notation,
perhaps "12N" and "12M", respectively. This would work for
English; ISO standards might require something like "12+"
and "12-".
Or we can all grit our teeth and use the "zero hundred
hours" and "twelve hundred hours" terminology.

Ostensibly there is, since in the 12 hour system people do actually use
such notation. That it doesn't seem to make sense when written down is
another matter, however, when we look at a wristwatch or clock one can
see where this usage may have originated.

That's "the decimal system", not "logic", even if I do agree that decimal
is nice.

Hmm. You'd thus divide the day into 10,000 units, which makes each unit
8.64 seconds long.

> You would, but I wouldn't.

I probably wouln't, either. Doesn't seem useful.

Now, if either you go SI and divide the day simply into 86,400 seconds, or
else change SI and divide into 100,000 parts. this might be useful - *if*
it was adopted by enough people. (A slight variation of the first actually
was successful. Unix uses seconds since 1970-01-01 00:00:00 GMT.)

Fortunately, the 24 hour clock above *was* adopted by enough people (most
of them, actually).

I placed the word between quotation marks deliberately, though my
reasons will appear obvious only to myself. In truth I don't really
believe in the possibility of any ultimate "logic"; everything we give
that name fails, always and inevitably, to live up to its promise.
All logic is human; therefore all logic is defective and open to
perpetual re-dedifinition ... rather like human languages. (Am I
being too logical, and therefore reasoning illogically?)

Logic-in-quotes might lead some dopes to conclude that, since
decimals are mathematically more efficient, the world ought to forced
onto a 10-hour clock.

True, but there's no need to repeat yourself when I haven't contradicted
you. It only causes confusion.

That qualification is probably unnecessary.

No, I wasn't challenging your "logically", I was challenging your
"indisputably". I thought I'd made that fairly clear in my first
sentence.

What I said, and you can check it above, is that there is another
logical way of interpreting "12:01 pm", and it happens to be the way I
interpret it, and it also happens to be accurate, unlike *your* logical
way.

To make things perfectly clear: "0:01 pm" is indisputably one minute
after noon; but one minute after noon is not indisputably "0:01 pm".

Does that mean that "logically" 2 am is two hours ante meridiem
(what's usually known as 10 o'clock in the morning)? And of
course 11:59 am is one minute after midnight.

Now this is turning into fun.

If you're serious about the above apothegm, you're telling us there
exists a Logic beyond human reason and definition; a Logic that, once
man attempts to apply it, eludes him; a Logic that cannot be defined,
discussed, or exercised, but can nonetheless be admired and invoked.

It sounds like the argument of either a mathematician or a theologian.

Well, kind of. It was spur-of-the-moment thing rather than a deeply
held belief.

>exists a Logic beyond human reason and definition;

Yes, in that human logic is a vain attempt to grasp the real thing. One
could state this less emotionally by saying that that human logic is a
useful temporary model that is constantly being refined; often, but not
always, in the direction of The Truth :-).

I would extend this idea from logic to mathematics as a whole; or, at
least, to what I learned in school as mathematics - it's probably
expanded a bit by now. I suppose "natural law" is another way of
putting it.

>a Logic that, once
>man attempts to apply it, eludes him;

If the application works, it works. That doesn't mean that the human
logic is True, it simply means that the model is reasonably accurate in
all important (to us) respects.

Even where this model appears *perfect* we should not mistake it for
absolute truth. History is littered with scientific "truths" that
turned out to be mere approximations or even completely wrong. The
present is littered with them also.

>a Logic that cannot be defined,
>discussed, or exercised, but can nonetheless be admired and invoked.

Well, we *are* discussing it... I think. At least we can discuss the
possibility of its existence; but we can never know it when we see it.

I suppose it all boils down to whether you believe that the path of
human scientific thought over the ages is wandering around at random, or
whether there's something absolute that it's headed for, is usally
getting closer too, but will never reach. I believe the latter.

Also neither.

ObUAE: I don't know any good language for expressing such ideas.

Agreed - Logic is just the machine that takes premises in one end and
spits valid conclusions out the other. 10 or 12 or 24 'hour' days can all
be logically justified, depending on the premises (I like the decimal
approach, therefore we should have a ten hour day) (I like proper
fractions, therefore we'll have 24 hours in a day). And yes, I know I've
missed out lots of other premises required to make these examples work.

You see nothing illogical about 1:01 pm being one hour after 12:01 pm?

Ooops. Hold it right there.

You're one of the people confusing subjects like mathematics with subjects
like physics.

Physics is finding out about the "real world". Mathematics, on the other
hand, is completely independent of the "real world".

In physics, theories only hold until disproven.

In mathematics, theories are proven, and hold forever from that point.

If someone tells you that there's no way to get antigravity, then you may
well expect that we later learn this was not true.

If someone tells you that it's impossible to sqare a circle, no such
possibility exists.

Physics, like all other natural sciences, works from observations to
theories that predict further observations.

Mathematics, on the other hand, works from premises to conclusions via
proofs. Observations don't go into this anywhere, except to get ideas
perhaps.

Physics is about natural laws. Mathematics is not.

Physics is about the ability to predict the "real world". Mathematics is
about Truth, with a capital T.

There's no absolute truth in physics. There is in mathematics.
There is no "real world" in mathematics. There is in physics.

These two are completely different sciences. (And, IMO, logic is like
mathematics, not like physics.)

Don't confuse the model with the theory (and don't confuse a mathematical
theory with a physical theory, these are completely different critters).

The mathematical theory is right.

The physical theory is essentially "mathematical theory X applies here,
with the following mapping of real world observations to mathematical
entities". (This is essentially a description of a model.) It can be good
enough, or not. It might even be true, but we will never be able to say
for certain.

The mathematical theory is right, or wrong. Usually, we know which. And no
observations in the real world can change anything about that.

Such observations can, of course, disprove the physical theory.

First one (not practicing, though :-))

Theology is significantly different, though: it's not possible to usefully
talk about theology without making reference to the "real world", just
like in physics. It *is* possible to do this in mathematics and logic - in
fact, it is usually done that way.

Simple example:

(x+y)*(x-y) = x*x - y*y

No reference to the "real world" there. (Of course, you'd really have to
reference this to a theory in which it is true (like number theory); but
that's often done by context, and in any case has no "real world"
references either.)

I find myself guilty of diluting and weakening my original point by
attepting to explain it in terms that I am more familiar with. My
original assertion was...

>I would say that logic is totally reliable; it is only the human
>definitions and applications of it that are fallible.

You have done a much better job that I could (did!) in expanding on
that. Thanks.

Since you seem to be supporting my point of view it seems churlish to
argue with what you say, but I can't help myself...

As a layman I find it hard to accept your assertion that mathematics
*knows* that it is The Truth. The Truth of the matter is, you can never
rule out the possibility that at some future date your idea of The Truth
will be shown to be false, or at least incomplete/approximate. That
last sentence is, of course, subject to the same rule. There *is* no
absolute certainty, only relative certainty, even in mathematics. IMHO.

Regards, Mike.

I see nothing illogical about 1:01pm being one hour after 12:01pm. Look

The French revolutionary committee tried it. I have seen a French
decimal clock in the Fitzwilliam Museum in Cambridge. It appeared to
have 100 minutes to the hour, but I never worked out whether there were
10 or 20 hours to the day.

There is nothing illogical about it. Further, there is nothing
illogical about 0:01 AM coming one hour after 11:01 PM. It may not use
the algorithm you are most comfortable with, but it is logical.

This is one of my pet peaves. Reference is not a verb, but I hear it
used that way a lot. In this paragraph, it is used as both a verb and
a noun.

"Reference" is indeed a verb. It means to include in something
references to something else. It simply shouldn't be used to mean "to
refer to." However, after 35 years, I've given up that fight.

One of my pet peaves is that dictionaries keep wanting to spell the word

Yeah, mine too. Well, it's good to throw in some humor every now and

This is not a logic problem, it's just a naming issue. Nobody said there
must be a rule that if B hours after A:D pm is C:D pm, then A+B=C must be
true for all possible values of A and C.

Granted, the system for naming the hours and minutes is not very sensible,
but that's due to tradition. The plebs weren't too at ease with the
concept of zero (see the discussions about when the millenium starts, and
about there being no year 0AD), and, besides, if the village clock were to
chime 0 times at midday and midnight, people might not hear it.

There are other examples of non-too-sensible traditions. For example, given
a street on which house numbers have been allocated in the usual, dense,
fashion, and then a new house is built inbetween number 3 and number 5,
assuming that number 4 is on the other side. Typically it will be called
3A, rather than re-numbering all the houses from 5 upwards. Now we have
two threes, one "3", the other "3A". Would it not be more sensible to
call them "3A" and "3B", and have no "3"?

Either way, though things may not be entirely sensible, they're still logical,
because it is possible to discover and to follow the reasoning behind them.

Why the devil should you want to do that? I'd think that what you want to
put before the quote (and after it as well of course) is a quotation mark.

"He referenced his homepage with URLs for related materials."

Note that I never said that anyone actually used it this way, just that it
existed and has been in dictionaries for a long time -- a factlet I had shoved
in my face in my early days of saying "'reference' is not a word" (something I
have long since learned not to say about *any* string of characters being
treated as a word).

I have the same preferences, I treat the quote, including its marks,
as if it were a word, and punctuate the containing sentence accordingly.
The quoted material may or may not include a dot (as I call it, it
peeves me to find it referred to, so inappropriately, as a "period"),
and if that results in occurrences of '.".', which confuse only the
faint-hearted (or faint-brained), then so be it.

I won't mention that in this case the quote *is* (potentially) a
complete sentence. Oh, darn, I just did.

No, it is not incorrect, it is simply a matter of style. It so happens
that the style you dislike is the one which is more prevalent in the US,
while the style which appeals more to us is more favoured in the UK.
