Hi! I'm Tulin. I think I am quite clever. I do quite well in science, english and maths for my age.
However.
I have never been good at reading the time. I never got it in Primary School, and I moved to Secondary School not getting it either. I'm now 14, and I can read it most of the time. Sometimes however I get stuck.
But moving on... I have been arguing with my friends for quite some time nows. And it is about a fact about time...
The fact that logic defies is the am and pm of 12.
It just DOES NOT MAKE SENSE!
1 2 3 4 5 6 7 8 9 10 11 12 <--- On the clock, the numbers are 1 - 12.
There are two groups of 1 - 12. 1 - 12 with AM, and 1 - 12 with PM.
For example, if this following group was AM...
1 2 3 4 5 6 7 8 9 10 11 12
^
This would be 1 AM
1 2 3 4 5 6 7 8 9 10 11 12
^
This would be 2 AM
1 2 3 4 5 6 7 8 9 10 11 12
^
This would be 9 AM
1 2 3 4 5 6 7 8 9 10 11 12
^
This would be 11 AM
1 2 3 4 5 6 7 8 9 10 11 12
^
So logically speaking, this should be 12 AM.
But it is not. It's actually 12 PM.
This really confuses me. It should either be 12 AM, (counting upwards) Or 0 PM (starting again).
Why do we have the 12? It is a nice number, but it doesn't have a real purpose - only to confuse me.
Have I explained myself right? Or am I just plain stupid? neutral

well i dont really know why their is the number twelve in time but it does round nicly, also in military time i beleive they go all the way to 24 hundred hours(just 24)
it would be all the number under and to twelve are their respective time (1 o'clock is 100, 2 is 200 ect) and numbers above twelve you just add one hundred to the last one (i.e 1 o'clock pm would be 1300 2 would be 1400 ect.)

dreams into nights yami well i dont really know why their is the number twelve in time but it does round nicly, also in military time i beleive they go all the way to 24 hundred hours(just 24) it would be all the number under and to twelve are their respective time (1 o'clock is 100, 2 is 200 ect) and numbers above twelve you just add one hundred to the last one (i.e 1 o'clock pm would be 1300 2 would be 1400 ect.) I do prefer that time - and I guess that wouldn't work for clocks. But for analogue time, why don't we have 0 instead of 12? It would make sense then.

12am is the hour that comes after 11pm. 12am is the 'official' start of a new calendar day based on our solar calendar.
a full 24 hour day:
12am (midnight)-11am (morning hours)
12pm (noon)-11pm (evening hours)
it's not really so illogical. maybe I'm just not understanding you clearly.
the clock that we use goes thru 1-12 because it's said to be easier for people to comprehend (at least I think that's why), as opposed to military time which actually goes from 0000 (midnight)-2300 hrs.

i cant say for the rest of europe but in scandinavia we use the military time...
i find it alot less confusing than the am/pm thing...
and just to make a point.. no we dont have all the numbers up to 24 on our clocks.. we just look out the window to see if its night or day ^^

in reality, 'time' is just a human concept anyway.

Actually I am usually user of the 24 hour system and not am/pm. The funny thing is, that I often use to mistake it and 12pm is for me in the night, such as 12 am the middle of the day is.

Basically, the AM PM deal is just to say where it's pre- or post- midday (noon). Time used to be kept in European villages by the church bells, which sound on the hour during the day, ringing for the number of hours that have passed since midnight, which was accepted as the "start" of the day. It becomes difficult to keep track of how many times the bell has sounded at around 13-20, and it's also easier to say "one o'clock, two o'clock, three o'clock" versus "thirteen-hundred, fourteen-hundred, fifteen-hundred."

You just have to learn the system and its meanings.

There isn't really a twelve AM or PM as it is only 12AM/Pm for a well not even a second so as soon as the second hand goes past the twelve has been 12 hours and one second leading it into PM and so carries on untill 12AM.... I hope that makes some sense....
