There is no such time as 12 am, because 'am' stands for the Latin 'ante meridiem', which means 'before mid-day'. Twelve hours 'before mid-day' can only mean midnight. ... A new day starts at 00:00, or as we commonly call it, 'midnight'.

As we normally count hours numerically adding 1 to the previous hour and as in a normal sequence 12 comes after 11 if it is then 11pm midnight must be 12pm and at the same time 00.00am so 1 minute past midnight is 00.01am the same applies to noon 11am being followed by 12am and at the same time being 00.00pm.

12.30 pm simply after noon. 12.30 am is simply after middle of the night. This makes experience, due to the fact the first could be very early 'afternoon' while the second may be very early morning. While we do tend to consult midday as 12pm and middle of the night as 12am, strictly talking this is illogical.

E. G. Richards in his book Mapping Time provided a diagram in which 12 a.m. means noon and 12 p.m. means midnight. ... For an example of the latter method, "midnight" is replaced with "11:59 p.m." for the end of a day or "12:01 a.m." for the start of a day.

Since noon is neither before nor after noon, and midnight could be considered the end of one day or the start of the next, neither label fits. However, it's a very common interpretation that 12:00AM means midnight (00:00 in 24-hour notation) and 12:00PM means noon (12:00 in 24-hour notation).

Another convention sometimes used is that, since 12 noon is by definition neither ante meridiem (before noon) nor post meridiem (after noon), then 12am refers to midnight at the start of the specified day (00:00) and 12pm to midnight at the end of that day (24:00).

Using numbers from 1 to 12, followed by am or pm, the 12-hour clock system identifies all 24 hours of the day. For example, 5 am is early in the morning, and 5 pm is late in the afternoon; 1 am is one hour after midnight, while 11 pm is one hour before midnight.

As standard 12:00 AM is taken as the start of the day. Time of the day is divided in two halves (24hour= 12 hours before midday + 12 hours after midday) so the 11 AM is 11th hour before midday as clock strikes 12 again it changes to PM (after midday) so it's 12 PM after 11 AM and 12 AM after 11 PM.

Is midnight today or tomorrow? What does midnight mean? To avoid confusion, it is always better to use the 24-hour clock, so that 12:00 is 12 noon. Therefore 24:00 Sunday or 00:00 Monday are both midnight meaning Sunday to Monday.

12:01 AM is one minute after midnight. The way to remember this is that AM = “ante meridiem” which means “before midday”, and PM = “post meridiem” which means “after midday”. ... Since noon is neither AM nor PM, we shouldn't technically call it “12:00 PM”, but rather “12:00 noon”.

Anything AM can be referred to as morning, and anything PM as night. Generally these will be broken into morning (AM), afternoon (PM), evening (PM) and night (PM). People sometimes confuse the earlier AMs because it's still dark outside, but 2 AM is 2 in the morning, not night.

Re: 12:00 noon/nn/ pm No abbreviation for "noon" since it is a short word already probably; however, you can use 12:00 a.m. or 12:00 midnight (or just "midnight") and 12:00 p.m. or 12:00 noon (or just "noon"). Of course, one can always go with 24 hour military time: 1200 = noon and 2400 = midnight. Bertha.

To avoid confusion, it is always better to use the 24-hour clock, so that 12:00 is 12 noon. Therefore 24:00 Sunday or 00:00 Monday are both midnight meaning Sunday to Monday. It is common for transport timetables to use 23:59 Sunday or 00:01 Monday, or 11:59 pm or 12:01 am, to further reduce confusion.

Both 12am and 12pm are precise moments of time. 12am is the exact moment the 12th hour of the morning finishes (am), and similarly for pm. Therefor 12am is midday and pm would start straight after. The confusion has started since the invention of the digital clock.

12:00 pm is 12 noon, while 12 midnight is 12 am! It is neither of the two. If you want to avoid the common ambiguity and confusion that is the source of this question, be explicit and say 12:00 noon or 12:00 midnight. Noon is usually 12 pm, simply by convention.
