Here's my brain. "Well maybe he was born on the 5th of... No wait there isnt a 13th month." This is just like the other day when i had to slap myself for almost asking why they didn't celebrate The Hitchhiker's Guide to The Galaxy on the 42nd.
That's the system we use in Britain. Personally I think it makes more sense as you say DAY MONTH YEAR usually more in normal conversations rather than MONTH DAY YEAR just learn to adapt to it
