Wikipedia - from a basic intelligence level you and or the American and Canadian International Convention is illogical and wrong!
00.01am is a minute past midnight - 11 hours and 59 minutes before 12 Noon.
12.01am doesn't exist because it is actually 00:01am; but 12.01pm (afternoon) does when using the 12 hour clock.
It is 59 minutes before 1pm.
Having reached the Twelfth division, the units return to zero, so technically 12:01 does not exist - especially just after Midnight and 12:01 only exists just after Noon in the 24 hour clock system.
Therefore the use of am and pm with the number 12 should be avoided at all costs, if confusion is also to be avoided.
Wikipedia is always right?
.....And all people should accept any any all absolutely absurd and confusing American and Canadian conventions which are 11 hours and 59 minutes adrift/apart.
Key Facts:-
11.59pm is 1 minute before midnight - so it's completely illogical that the missing kid was last seen between 11:00am and 12am - so he was in the same place for 13 hours then? 13 hours or 1 hour in one place - I think most probably 1 hour between 11am and noon but the police didn't correct or clarify their tweet. Nor did they quote Wikipedia with all quotes from American and Canadian Sources.
....12pm is 11 hours and 59 minutes later!?
Similarily 12:01pm is 1 minute after 12 Noon and not 1 minute after Midnight - that is 00:01am
If you, the Americans, Canadians and Wikipedia are all right then the kid was seen/observed for 13 hours!
Think we need to use British English and sensibly avoid using the am or pm suffixes; but instead use the terms Noon, Mid-day or Midday and Mid-Night or Midnight.
It is therefore well advised to drop the use of 12am or pm because there is confusion and people can easily be 11 hours and 59 minutes early or equally,12 hours and a minute late - or is it the other way round.
More intelligent to say 12 noon, Mid-day/Midday and use 12 mid-night/Midnight or just midnight for 24:00 if not sensibly using the 24 hour clock.
Digital Clocks need correctly reprogramming to avoid 12am and 12pm and convention needs amending to apply colloquial and general terms used in the every day universally accepted British English Language.
The difference is as plain to see as Night and Day!
Conclusion regarding the Time and Clock Convention.
General Analogue meter reading conventions.
When reading an analogue gas or electric meter - or any meter for that matter, it is read backwards and not forwards. That is to say that a Seven stays a Seven until the next unit/dial zero has passed through zero, which then simultaneously changes the Seven to the next whole number, namely an Eight. To read the Seven and Three quarters as an Eight for the whole set of dials would give a dramatically inflated reading and subsequently a very very high Gas or Electric bill.
A clock is a measuring device or meter and so therefore to read it accurately and correctly the same conventions need to be applied. Using this principal, in the case of a clock and time it is still in the Eleventh hour until it actually passes the twelve. There is no Twelfth hour time period and so therefore it stays am until precisely Twelve o'clock plus a fraction of a nano second. When using a twelve hour system the next unit after Twelve is Zero and Zero plus an infinitely small proportion of a nano second is 00:00:00:01pm. So am does not become pm until a very small fraction of time after Twelve o'clock and therefore up until the change to pm the time actually still remains am. Incorrectly reading forwards causes an increase of Eleven hours Fifty Nine Minutes and a large number of nano seconds. The logical and analytical difference when explained correctly in this way is as plain to see as Night and Day!
A comment on the Twelve Hour Clock.
It is very important to remember that a Twelve Hour Clock has only Two divisions of Twelve hour periods and that the Thirteenth Hour does not exist. An am time period ends at 12:00 and a pm time period starts immediately the time has passed a split nano second after the Twelfth hour and begins at zero. So technically speaking there is no true time of Twelve Twenty in the use of the Twelve Hour Clock for example. It is a misnomer. Twelve Twenty does exist, however, in the Twenty Four Hour Clock.
