The use of AM and PM to designate either noon or midnight can cause ambiguity. To designate noon, either the word noon or 1200 or 12 M should be used.(EB)
but one does get confused.
There is absolutely no ambiguity about the am/pm issue if one thinks about it logically.
The key thing to remember is that the am/pm change can only occur at exactly 12 noon and at exactly 12 midnight. So if you know that 11:59 in the late morning is 11:59 am, there can be no doubt that 12 noon is 12 pm.
Another way of knowing that 12 noon can not be 12:00 am is that 12:00 am can not be followed one minute later by 12:01 pm. (see the above underlined)
I would like to point out that I was merely quoting from Britannica Online Encyclopedia (although apparently the quotation marks somehow got lost on the way)
so maybe this would be the place any suggestions for linguistic improvement should go to.

thanks a lot all of you,
to me it's always easy to understand when there's some logic reason involved. in this case, i will always remember the meaning of am/pm simply by translating it to Latin, once that my native language is a Latin one.
