I originally posted this on the other site back when I took the picture, and it resulted in a lot of confused comments, especially from Americans, eventually getting removed by overzealous mods. Either way, I promise you that this date does not exist, and has never existed.
Written has ambiguity, spoken doesn’t. One has to be standardized and the other doesn’t.
The topic is about written, not spoken since we all completely comprehend this.
I disagree with that assumption.
The comment I was originally replying to was talking about the two most debated formats while ignoring ISO for “non-technical” people. Those two formats are that way because of the way people most commonly speak it in the region where they originated. I agree that the best written format is ISO, but it’s not commonly used outside of technical circles because it requires that you say it in a different order than you read it, which proves difficult for a lot of people.
