Date Picker won't go prior to 1999

The date picker calendar only goes to 1999. This causes problems for at least the birth date field. For example, I initially typed in a birth date of 7/2/1985 and saved it. Then when I went back and opened the calendar it opened to July of 1999. As long as I don't change the year it will leave it as 1985- even though it says 1999. But if I change the year there is no way to get back to 1985 without typing it in.
