I know that the US English uses mm/dd/yyyy and the Queen's English prefers dd/mm/yyyy (and so InE).
Now imagine Mike from New York City is writing a letter to Joe in London. And the letter is official, to be filed for future reference. What format would Mike choose?
Will he stick to his format OR will understand that this is for Joe's future reference and since he knows the UK format, he'd prefer writing dd/mm/yyyy?
While it's easy to identify it from the numbers used, it is impossible to make out when the months and dates are below 12. Say...
4/8/2014 - Is it August 4 OR July 8?
I'm asking to both the native speakers -The Americans and Brits.
