However, there are ways to avoid the confusion completely: you could write 12 noon or 12 midnight instead. Alternatively, you could use the hour clock system, where is noon and or is midnight. As standard AM is taken as the start of the day.
Late night. The term we associate with the morning, a. The greeting good morning can be used anytime after break of dawn until noon in the afternoon. The time between noon p. Similarly, midnight is am and am is 59 minutes into the next morning.
To add or subtract times, fill out another time on the left and hit the plus or minus button. To multiply or divide, enter a number on the right and hit the multiply or divide button. In all cases, the result will be displayed at the bottom. Hint: The abbreviation a. Using numbers from 1 to 12, followed by am or pm, the 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.
Evening is from PM to 8 PM, or around sunset. Night is from sunset to sunrise, so from PM until AM. The first hour period is designated as am. It runs from midnight to noon. The second period, marked pm, covers the 12 hours from noon to midnight. The abbreviation a. Skip to content April 20, Joe Ford. This applies to both 12s. Is there an authority on the subject? At least there will be no confusion then.
Jules Smibert, Gold Coast Australia 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 It starts at , which would mean that would be 12am and then would be 12pm. It depends how you classify a day, if it runs from until then 12am is noon and 12pm is midnight. If it runs from until then 12am is midnight and 12pm is noon, but surely we all agree is not a time?
Think how many computer operations could take place unnoticed in that no-man's land of a whole second second! Just make sure you specify the appropriate day.
Midnight and midday are neither am or pm as explained in the GMT link he provided. As 'x' approaches zero it never actually gets there just as it reciprocal never reaches infinity. Gary Reid, Wollongong Australia Midnight is neither 12pm or 12am, there is no such time. Midnight is 12 midnight and mid-day is 12 noon. All other usage is sloppy. As one reply says the armed forces use and George Redgrave, Crawley United Kingdom The disagreement about midnight stems from the fact that it is a boundary between two days.
There is no reason to prefere one over the other except a desite for standardisation. Following this, it is obvious that this same moment in time can also be called 12pm Monday because it is 12 hours after the Monday meridian or 12am Tuesday because it is 12 hours before the Tuesday meridian. The very fact that both of these positions can be defended is reason to never use either. Similarly, noon is the meridian and is therefor neither am nor pm.
We only call it 12 o'clock because of the number on the dial. There is no logical reason why this number cannot be replaced with a zero. It is simply noon. Since we do not notate time backwards, 12 midnight is not 12 am, since it would then require 1 am to become 11 am and so on. Similarly since it is the fleeting instant that marks both the end of one day and the beginning of the next it belongs to both days and to neither ,it is not 12 pm.
In reality midnight has no sooner been reached than it has been passed. The phrase "the stroke of midnight" is apt. As has been demonstrated by many of the previous answers, and because it is incorrect, the use of 12 am and 12 pm is inherently confusing.
To avoid this confusion it should be ended. The use of noon and midnight informally or 12 noon and 12 midnight or and should become practice. Bernard Maguire, Glasgow Scotland I have had fun reading all these answers. However, I have always held the fact that 12pm is noon. Example: Counting in minutes, you would have am, am, am, am etc. Therefore it stands to reason you would have: am, am, pm, pm. It would just be odd to have: am, am, am, pm John Wood, Sheffield, England Use 12 midday or 12 midnight for clarity.
It is easy to call others morons. We need to realize that a clock gives us a means of reading time. Time is a fluid, always changing value. It is never what the clock says it is. Noon and midnight are for a infinitely small period of time as is any number on the clock represents. An example is the only clock that is correct is the one that is stopped. It gives the correct time twice a day. A running clock is always wrong. By the time we look at a clock that tells us it is noon, it is past noon and the same at midnight.
So where does that leave us? When the time reaches noon, it is PM. When the time reaches midnight, it is AM.
