Good, we want you insane.
I always understood the American date format(MM/DD/YYYY) as Month Day-th Year, because they're lazy and it's more convenient for them to say.
The Normal format though(DD/MM/YYYY) is more practical though, just like the metric system. You know, each unit being 10 times smaller or larger than the next one, not 12 inches being a foot and however many feet being a yard.
Fun fact for us metric people, (I haven't done research on this) but I've heard that the one who made the metric system pretty much mainstream was Napoleon. Which means we're using a french system. :/
