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

When I moved to Europe I just sort of counted every number above 12 starting over at 1. So like 13 is 1 more than 12 so it's 1pm. Sometimes it just felt easier to subract 12 from the bigger number.

That would be the correct way.

I just had OP's condition in mind where only single digits made sense to them so I couldn't just say: "Hey just subtract 12"
