Modular arithmetic is easy enough to learn. Even Children can do it.

You are really talking about Metric Vs Imperial units and the mind sets 
required to use them.

An interesting topic.

No, no. No "imperial vs metric (is better)" here.

Just the strange counting : 11 AM, 12 PM, 1 PM, 2 PM...
 11 PM, 12 AM, 1 AM, 2 AM ...

India is far far far away land, but the invention of 0 could have
reached every part of Earth by now.

You have 11 golden apples, add one apple, what do you get ? 12
apples... red ?

If at least 11AM was followed by 12AM. At least the military fixed it.

No, maybe I am too young... I vaguely remember having lessons on the 24 
hour clock at school, must have been about '86.

Thinking about it, every digital clock I use is in 24 hour format, I 
thought it was only my mum who still used the 12 hour clock. She had 
obviously reset her car clock at some point, as it was 12 hours out of 
sync, showing "19:45" on the way to work!

I am a bit older and Continental time was thought of as one of those 
cute oddities that "the Continent" had. Along with tooth picks and not 
putting olive oil in your ear.

Nope! She is not the only one.
I use the 12hr clock in my personal life and, depending where I am 
working, the local preference. I've missed a couple of trains that way. 
Sitting in the pub thinking that I have an extra couple of hours.

I wonder if she even noticed?
Except for 20:00 and 24:00 I automatically translate the time into 12hr.
The except for, is why I've missed trains. :(

Yes, it does sound better, in English. I was just being polite.

Again it is mind sets. The 12hr clock system is not continuous. There 
is; before noon, noon, after noon and midnight. Noon and midnight are 
instants.
So we have the eleventh hour of the day followed by midday followed by 
the first hour after midday. Calling noon and midnight twelve o' clock, 
is just for convenience.
So having grown up knowing that. It is as obvious as, one is 1 and two 
is not too.
Add that to a dozen inches in a foot, 5280 feet in a mile and sixteen 
ounces in a pound. You get units that you have to think about when you 
use them. Surely you don't think having to use your brain is bad?

I never thought about that before.  That is funny.

Arguably, it does make sense.

The abbreviations "AM" and "PM" mean "Ante Meridiem" and "Post Meridiem" 
- ie, before the middle and after the middle.

So it makes sense (in that regard) that 12 PM precedes 1 PM, since 12:00 
is the dividing point - and usually I hear "12 Noon" (or just "Noon) 
rather than 12 PM - but 12:01 PM is the first minute after the middle of 
the day.

The reason it doesn't make sense is because the switch from AM<->PM 
occurs an hour earlier than the "wrap around" of the numbers (12 back to 1).

If it went .. 10AM, 11AM, 0PM, 1PM, 2PM ... 10PM, 11PM, 0AM, 1AM ... 
that would make more sense.

Oh, yes, I understand that numerically it doesn't make sense.  But from a 
meaning standpoint, it makes perfect sense.  AM/PM have to do with 
midnight/noon, nothing to do with the numbers.

You are as well telling them that the Inch is better than a hundredth 
part of a yardstick. ;-)

Will they ever listen?
No! nay! never, no more.
