Draw a 24 hour clock and then get into a fight over whether it should be noon or midnight at the top.
I don’t understand this clock questioning. If they don’t stipulate that 12 high is at midnight or is at high noon, it has no purpose. And what about those who have grown up with digital clocks? What a silly test for cognizance.
An assisted living facility nearby had a couple of WWII submariners retired there whose sleep times were, as old as they were, at different times in 24 hours. They’d wake say at 6PM and think it was the next morning looking at their regular clock.
Solution was putting up 24 hour military time clocks, like the ones on WWII era submarines (this was to address the fact that time underwater has no reference to “light coming up at dawn” or down at dusk etc.)
So the number at the top of the clock is “00” then 1, 2,3 etc down to the 6o’clock position on a standard clock—which is “12”. Then on up from 13:00to 23:00 hours the last marking before 00 which is the end of a 24 hour cycle.
It really helped these men know what time it really was and helped keep them less confused. They knew from that clock whether it was 3 AM in the morning or 3 PM in the afternoon.
For those non-military here is what the clock looked like:
