Are you trolling or just incapable of acknowledging that you can speak a date differently than its written representation? The entire reason for any standard is just to ensure you’re working within a known/consistent framework. You can measure in imperial or metric but you can’t label an imperial or metric unit as the opposite just because you prefer it that way.
If I hand you glass of milk with a skull and crossbones sticker on it why would you assume it’s harmful when in my region it’s used to signify its high calcium content? I can say “poison” or I can say “milk”, but a skull should never be interchangeably used.
In the same way, a date written in a global standard format should always be immediately recognized as signifying ONE particular date, and you’re then free to localize it however you please.
