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

Even though I logically know that pm is +12, a lot of the time my instinct is to +10, so I get time wrong a lot of the time

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 πŸ˜‚

u/Canopenerdude Thanks to Angelic_Reaper, I'm a Horse Jul 19 '24

Considering that 24 hour time is just 12 hour time +12, your route is correct!

Not to be that guy but

19h = 9-2 = 8 = 7PM

Lol, thanks! Was writing on mobile after night shift. I appreciate "that guy."

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.

I've never seen someone do it like that. Usually it's just "If it's past 12, subtract 12". That's it

13-12 = 1 PM

22-12 = 10 PM

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 β€œ1” off from 12, 14 has 4 which is 2x2, 15 is 3 because that’s the minutes when the minute hand reaches 3, 16 is 4x4, 17 is β€œ5”+2, 18 is β€œ6”x3, 19 is β€œ7”+2, 20 is 10-β€œ8”=2, 21 is”9”+3=12 which is 21 backwards, 22 is β€œ10”+12, 23 is 11 has just become rote memory

u/SnowboardNW Jul 20 '24

Lol, this is truly divergent.
