There is no such time as 12 am. am stands for "before noon" and before noon cannot be noon.

A.M. is the initialism for the Latin ante meridiem, meaning "before noon/midday."P.M. stands for post meridiem, meaning "after noon/midday."So AM is the morning (before noon) and PM is the afternoon and evening.

Proof: P{T>n+m/T>n}=P{T>n+m,T>n}/P{T>n} (Bayes theorem) =P{T>n+m}/P{T>n} =((1-p)^(n+m))/(1-p)^n = (1-p)^(n+m-n) = (1-p)^m (1-p)^m = {T>m} So T>m has the same probability as T>m+n given that T>n, which means it doesn't care (or don't remember) that n phases had passed.
Ante Meridian: before noon - am Post Meridian: after noon - pm
AM - Ante Meridian, Latin = "before midday". Before noon PM - Post Meridian, Latin = "after midday". After noon
Modern digital clocks display "PM" at exactly noon, so that has become sort of a de facto convention.If you examine what "am" and "pm" mean, you get another story. "AM" is an abbreviation for the Latin words meaning "before noon." "PM" is an abbreviation for "after noon." Noon is neither before noon nor is it after noon. The "M" stands for the Latin word meaning "noon." So in old documents, you may see twelve noon referred to as "12:00 M." Of course, that is confusing to most people because the word "midnight" also starts with an "m." The use of "m" (meridian) to mean noon has fallen out of favor in modern usage.Confusion abounds as to the correct usage. If at all possible, you should try to use 11:59 am or 12:01 pm to avoid confusion. If that is not possible, just say 12:00 noon.
If you mean "a. m." as in telling time, it means "ante meridian," Latin for "before the middle [noon]."
The P stands for Post and the M stand for Meridian.From the Latin, Post means after, and Meridian means midday (noon).So the abbreviation PM as it pertains to time stand for after-midday or afternoon.
after m, before p
