First, I am very sorry I missed, this one, it sounds as if it was great. However, Mbo, how wrong you are when you say "No one has ever had any problems with it." Coming from a family that constantly moved back and forth between the French and American systems (so 5/6 was either the 6th of May or the 5th of June) and we have missed planes, concerts, birthdays, you name it, because the Americans don't put what you need most to know, first. Generally you know what month it is, and it's the exact day you're looking for, so 6/5/00 makes more sense to me as it's the 6th (and I already know it's of May, 2000) than as yeah, it's May, OH yeah and it's the 6th.

My eldest sister circumvented this with both her daughters, born 7/7 and 4/4, so as they move between school systems at least that part doesn't matter.
It also took me forever to stop writing my name last name first, and now that is what American forms have changed to... but I still cross my 7's!
