The world has a lot of different standards for a lot of things, but I have never heard of a place with the default screw thread direction being opposite.
So does each language have a fun mnemonic?

Here is clockwise. One arrow is going to the right and one to the left.
I tend to agree but you could argue that from a perspective in the center of the rotation you’re turning to the right. Imagine standing in the center of those arrows.
What happens if you look at it from the other side?
The whole thing is rotating to the right, that’s what clockwise means. Clocks rotate to the right. One arrow is not pointing left, it’s pointing in the direction of rotation, which is to the right.
The bottom arrow is, definitionally, pointing left.
You think this arrow is pointing to the right, when it is clearly pointing up and to the left? Fascinating.
If you follow that arrow around to the next with your hand, which direction is your hand moving?
That is indicating clockwise rotation, or a rotation to the right. We’re talking about circles here
Wrist is going left.
If I start at the beginning of the arrow and follow it, it’s moving left.
Is the direction of rotation in the room with us right now?
