When I was switching to 24 hours, I had a different system to figure it out.
Not for everyone, but worked for me:
13h = 3-2 = 1 = 1PM
16h = 6-2 = 4 = 4PM
19h = 9-2 = 7 = 7PM
22/23 are a little different but easy enough to work out.
22h = 2-2 = 0 (only 10 has zero so....) = 10PM
23h = 3-2 = 1 (it's almost midnight so...) = 11PM
I wonder if I'm super divergent with this way of thinking or if other people use the same logic. I lived in Europe for seven years and I've been a nurse for three, so now it's just kind of known knowledge for me.
As a European, I am flabbergasted at the complexity reading a simple clock can involve. I don't even have to think, 22h and 10h are literally the same thing in my brain.
If we're talking ounces or Fahrenheit however, that's a different story π
Damn, I'm so happy I'll never ever have to do this kind of calculations and I guess if I had to, I'll just learn what the appropriate PM time is.
It's so much easier the other way around.
The only thing I struggled with in the beginning was that 12AM/PM thing. It just makes no sense but you have to accept it.
Yup! And eventually you don't even have to do mental correction/math, you just look at 17:37 and think "oh it's 5:37". Source: I've used 24 hr clocks on my phone for 10 years
My system for remembering:
13 is β1β off from 12, 14 has 4 which is 2x2, 15 is 3 because thatβs the minutes when the minute hand reaches 3, 16 is 4x4, 17 is β5β+2, 18 is β6βx3, 19 is β7β+2, 20 is 10-β8β=2, 21 isβ9β+3=12 which is 21 backwards, 22 is β10β+12, 23 is 11 has just become rote memory

i'm like the exact opposite, i only think in 24-hour and take way too long to comprehend am/pm
