When does am and pm change?
Keith R Baker
is 12.00 pm midday or midnight? and at what transition does
am become pm?
Is there some sort of official reference for this - preferably on the
web or can someone quote me the appropriate bit.
Thanks
Keith

p.m. begin with the first moment past the stroke of 12. Confusion could be
eliminated if all went on 24 hour standard time....Egad, think of the hundreds
of new watches and clocks that would require!!!!...(not to mention all the old
collectable watches it would create!!!!!!!!)....Anyway, to avoid such confusion
when dealing with the unaware, I simply designate 12 n. for midday and 12 m.
for midnight....that ought to help further the confusion !

Further the confusion? Actually I think it solves it.
I work in a 24hr/7day job. I would prefer if many more people expressed
time in the 24 hr manner.
Instead of 12 AM or 12 PM, I use the terms 12 noon & 12 mid. It saves all
of the confusion which initiated the original post.

Actually, it is most correct *not* to refer to midnight and noon as
being "post" or "ante" meridian, "p.m." and "a.m." respectively. At
12:00 O'Clock noon, the sun exactly crosses the meridian, and its
position is neither before or after the meridian, but dead on it.
Because we live in the age of digital displays, we expect that each
moment of time must have an indication of a.m. or p.m. Not so!!

Noon is customarily 12 pm and midnight is customarily 12 am.
Personally I enjoy a little ambiguity in my life. 24 hour time, like
the metric system, is for Nazis.

long hand of the clock points to 12, and the short hand
points to 1, the time is 13:00.

12:01pm it would follow that 12:00pm is noon. Remember last New Years
eve? The New Year started the second the ball fell. That would be the
second after 11:59:59pm

Strange, yes. If one agrees on a 24 hour cycle, the cycle is
certainly not completed until the count has reached 24,
no matter how small that difference might be. The last count is
24 - not zero.

Then they would appear to be missing a minute. (Probably 0000).

The above statement is the opinion of the author. No endorsement

Really, I wouldn't kid you about a thing like this.

post meridian however 12.01 a minute after noon is PM and so is 12:00:01 as
only a second after noon. Surely by truncating 12:00:01PM we get 12PM.
Thus 12:00 is range of times 12:00 to 12:00:59.
So it seems logical that 12 noon can be refered to as 12 pm even though its
is
12 noon and not 12am or 12pm.
Does any of this makes sense?

negative number -- yes, your answer makes sense, 12:00:00 is "M".
Now if someone could provide an equally satisfying, suitable label
for 24:00:00, we might all finally get some sleep. Let's call it "W",
shall we? :-)

PM is the period when it sets, then we can go to the starting point of our
measuring system and the first number we use to count is of course 1.
Weather it is one second or one minute or one hour or one day or one year.
We do not counting from the start of our period, but only after a period of
time has passed do we count 1 and after another period we count 2. This can
be continued untill we get to 59. We still have another period to pass
before we count one hour. Continue this resoning untill you get to 11:59 and
you find that 12:00 is the end of the period that we call AM and the sun is
high in the sky. Imediatly thereafter we enter the PM period and it
continues untill midnight. The same reasoning is applied to the year 2000 and
the turn of the century. The 21 century does not start untill the year 2000
is over as it is the last year of the 20 century. Regard Joe
