12:00 AM equals 00:00.
From 00:00 to 11:59 (of a 24-hour clock), the time is represented as A.M. Between 12:00 and 23:59 (of a 24-hour clock), the time is represented as P.M. A.M.
In the 24-hour time notation, the day begins at midnight, 00:00 or 0:00, and the last minute of the day begins at 23:59.
00:00 = 12:00 AM
00:00 on a 24-hour clock is is 12:00 AM on a 12-hour clock. This system is used throughout the world (not just the military) and leverages a 24-hour time clock rather than the 12-hour AM/PM system known to most English speaking countries.
As the dividing point between one day and another, midnight defies easy classification as either part of the preceding day or of the following day. Though there is no global unanimity on the issue, most often midnight is considered the start of a new day and is associated with the hour 00:00.
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).
Morning technically starts after midnight. However, 3 a.m. is too early to be considered part of the daytime. For most of the world, it is still dark outside at this time and most people are sleeping. So, 3 a.m. is considered night.
To avoid any confusion (and to make sure you arrive on time), it might be best to say 12 noon or 12 midnight instead. Alternatively, you could use the 24-hour clock system, where 12:00 is noon and 00:00 (or 24:00) is midnight.
The American Heritage Dictionary of the English Language states "By convention, 12 AM denotes midnight and 12 PM denotes noon.
But 0:00 is midnight. And 12:00 is noon–or midnight. Okay, 0:01AM means something.
There is no a.m. or p.m. in military time, as numbers are not reused, but instead, each hour has its own number. Any given time of day is expressed in four digits. The day in military time begins at midnight with 0000, pronounced "zero hundred hours" or simply "zero hundred."
It depends on who you ask! In the U.S., 12 AM is considered midnight, while in other parts of the world 0 AM is considered midnight. So it really just depends on your location! It can be written both, 12 AM or 0 AM.
8:00 a.m. Explanation: AP style is to omit :00 when a.m. or p.m. is specified.
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. Ante meridiem is commonly denoted as AM, am, a.m., or A.M.; post meridiem is usually abbreviated PM, pm, p.m., or P.M.
As midday is meridiem — that is, midday, the mid-point around which the other times are ordered — it cannot be said to be post itself. Therefore, 12:00pm is not a real time. QED, etc. Against this argument is widespread usage: 12pm appeared in government gazettes well before Australia ever federated.
Midnight is a part of the day that is ending, not the day that is beginning. When expressing times for “noon” and “midnight” it is best not to use numerals (12:00 a.m. and 12:00 p.m.). Avoid the redundant 12:00 noon and 12:00 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.
P.M. is used to represent evening and not morning. P.M is the time from noon to midnight. It is Pre Midnight or the time before midnight.
This all depends upon how late, and how regular, a person's sleep patterns are. For example, falling to sleep at 4 am and waking at 12 pm will cause a person to miss out on a large amount of daylight, especially in winter. This can be problematic for various reasons, including our physical and emotional health.
Waking up in the middle of the night is called insomnia, and it's a common problem. Mid-sleep awakenings often occur during periods of stress. Over-the-counter sleep aids rarely offer significant or sustained help for this problem.
It's no surprise that midnight is the very middle of the night, the word itself stemming from the Old English mid-niht, from mid, "among" or "in the middle of," and night, from niht, which appropriately means both "night" and "darkness."
