Personally, I prefer the ROW format, dd-mm-yy which makes 4-7-74 palindromic.

-Diego-'s friend, had the 4/7 vs. 7/4 work in my favour, as I was able to rent a car when I shouldn't have!
I arrived in Kalamazoo, MI, on a very delayed flight, at about 1:30am in May of 1999 (2 months before my 25th birthday).
I had to collect a rental car, and was aware that lots of rental companies refused to rent to under 25s. Budget was generally (for an extra fee, of course) the only one that would. Sadly for me, 2 out of 3 rental counters (Budget & Hertz) were closed until morning, Enterprise being the only open one.
I inquired as to the possibility of renting to a driver under 25, to which the response was "Under no circumstances, you'll have to wait for Budget to open."
Faced with the possibility of spending a night in Kalamazoo airport,
*shudder* I had an idea. Presenting my UK licence (dd-mm-yy format 04/07/74) to the same guy at the Enterprise desk, I asked to rent a car! Clearly bemused as to why I'd even asked about rentals to under-25s he proceeded to enter my date of birth into the rental agreement (mm-dd-yy) as 04/07/74. Thus making me 25 on the 7th of April, and allowing me to drive away to a welcoming hotel bed! Thankfully nothing happened to car during the 2 weeks I had it, or I'm sure there'd have been certain "insurance" issues, but I could've pleaded ignorance and claimed their employee made a genuine mistake!
