The confusion has started since the invention of the digital clock. Well, I think of it this way: Midnight is an exact moment, the border, between the period of time after noon of the day ending pm and the period time before noon of the day beginning am. I think of am and pm as periods of time between midday and midnight and not inclusive of them.
M is ridiculous. The argument that it is both ante and post midday does not hold. It is only both because you are using two days instead of the specific day you are talking about. It is A. To argue that it is also P. M post mid-day is irrelevant because it is only post mid-day Sunday not Monday.
If you say 12am Monday there is no reason to confuse the P. 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. In English, do we use the hour clock or hour clock?
In other words, do we say for example 2pm or ? In general conversations and situations in English, we use the hour clock format. In practice, that means counting the hours from 1 to 12 in the morning and in the afternoon. I usually have breakfast at about — we have breakfast in the morning.
Sometimes, such sentences can be unclear :. His plane leaves at Is that am or pm? Planes leave at both those times. They sleep at night. What time is it? Is 12am morning or night in UK? Is 12am in the morning? What is 12am in 24 hour time?
