If you are doing dates the nice way as yyyy/mm/dd you should use dashes - ie yyyy-mm-dd. Let the slashes mean other styles.

Or you could not make assumptions like this. There are more ways to represent dates than there are bones in my body. What seems like a silly way to you might be the preferred way for someone else, for a variety of reasons.
