From this website in a thread called "American vs British style of writing dates":

What a stupid discussion:
Fact is:
Both day-month-year and month-day-year are used in Britain. And the month-day-year version is even preferred by British newspapers:
Let's see:
The Times: February 17, 2005
Guardian: Feburary 17, 2005
Economist: February 17th 2005
And there are also influential American publications (especially academic publications) that use day-month-year, for example:
Science Magazine: 17 February 2005
Physical Review Letters: 17 February 2005

and from Saturday's Times of London, check out the date, September 5, 2009:
.
When using all numbers, written, you’ll never see anything other than dd/mm/yy or dd/mm/yyyy in common use.
Completely misses the point. The issue isn’t how Britons write the date with the month spelled out, i.e. “September 5” or “5 September.” The issue is how they abbreviate it: “9/5/2009” or “5/9/2009.” The discussion you linked to only addresses that in passing, and doesn’t cite any examples of the “American” form being used in Britain.
