This cannot be changed to a date format of DD/MM/YYYY by changing the browser language to any variant of English. It will always default to the US date format. This is by design.
If the internet browser language is changed to another non-english language, such as German, then the date format will change to DD/MM/YYYY but all text will be in German.
