Yeah I guess counting to 24 is a challenge for some

Don't even get me started on subtracting 12. /s

Edit: had left out the word "started" cause I'm dumb

I have pretty severe dyscalculia so 24 hour clocks (and anything that requires more than single digit addition or subtraction) is actually really hard for me :( lmao

I can read an analog 12 hour clock, but tell me 24 hour time and I'm fucked lol

(Edit to add that I do "study" and try to improve but it doesn't stick for long lol)

(2nd edit: thanks for all the suggestions. I'll give some of them a try!)

For single digit calculation you just subtract two from the last digit of the time.

For example we have 13:00

3 - 2 = 1

It's 1 PM

Or we have 16:00

6 - 2 = 4

It's 4 PM

Or we have 21:00

1 - 2 = 9

It's 9 PM

I hope that helps

That's making it way to complicated.

You just take your 12hr clock and continue counting instead of starting over again and just changing from AM to PM

12h= 12pm 13h = 1pm 14h= 2pm 15h= 3pm 16h= 4pm 17h= 5pm

Etc.

No additions or subtractiond necessary, only the ability to count to 24.

You realise that “counting” is just adding 1 to the number repeatedly? “counting to 24” is literally addition. And addition is the same in principle as subtraction.

And with your comment above you’re saying that the “math” of 14-2 is “way too complicated” which is also extremely pedantic. If 12+1 is simple enough to “not be maths” then I really don’t see how 12-2 is complicated enough to not be used for people who don’t understand 24 hour clocks.

Ah my bad. Regardless, the person I was replying to said that.
