> "04/05/2020", you have no way of knowing whether it means crazy American dates

In just about every professional setting I've been in (in the US), Americans are just as confused as everyone else. We deal with people and documents/data from the entire world too. We look for clues elsewhere, such as other dates from the same source that have any number greater than 12, etc. There are very few documents these days where you be 100% confident without some other confirmation.
