Not entirely sure what the complaint is. I know HN is skewed very US heavy - but most of the rest of the world uses D/M/Y. I for one find M/D/Y bonkers ¯\_ (ツ)_/¯
But you only know at this point in time that it's d/m/y because otherwise it would be a date in the future. If it said 10/03/2022, would you know if it was in October or March? This causes needless confusion when there's better alternatives for date formatting (e.g. y-m-d).
