122350
There are no standards established for the meaning of 12am and 12pm. It is often said that 12am Monday is midnight on Monday morning and 12pm is midday. This puts all the times beginning with 12 and ending with am in the same one-hour block, similarly with those ending with pm.

Noon (or midday) is 12 o'clock in the daytime, as opposed to midnight. It is written as 12 noon, 12 p.m. (for post meridiem) or 12 pm. Solar noon is the time when the Sun appears to contact the local celestial meridian.

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.

AS IS clear from consideration of the literal meanings of am and pm, noon is 12m, while 12am and 12pm have equal claims on midnight.

Midnight – and noon – aren't defined as a.m. or p.m. You can talk about 12:01 a.m., and you can talk about 12:01 p.m., but 12 o'clock a.m. and 12 o'clock p.m. mean different things to different people. ... In that system, tonight's midnight is the first moment of 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.

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'.

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”.

There is no exact definition of the time when afternoon ends and evening starts. (This is equally true for "evening" and "night".) However afternoon is often taken to start directly after noon (12:00 pm). Afternoon ends and evening starts at roughly 6 pm or maybe just before sunset.

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).

Originally Answered: Why do we call 12 p.m. noon? The term 'noon' comes from the Old English 'non', which in turn is derived from the Latin 'nona hora' -ninth hour. Originally it referred to the ninth hour after sunrise - that is, 3pm. During the twelfth century, the meaning began to shift from 3pm to midday.

Technically, it is correct only to call it 12:00 noon. Summarizing what others have written, the half-way point of the day, known as the meridian, is 12 o'clock noon. Since it is the meridian, it is not technically correct to call it either AM (before the meridian) or PM (after the meridian).
