No, they are declared as datetime, which means that they are in a
binary format. If you say

SELECT * FROM tbl WHERE datecol = '07/01/05'

You could get rows from from 2007-01-05, 2005-01-07 or any other
of the six possible permutations, depending on the current settings.
On the other hand:

SELECT * FROM tbl WHERE datecol = '20070105'

will always give the same set of data.

OK, so that is not what you asked about, but since you had an apparent
misunderstanding about datetime, I figured I should point it out.

If I understand this correctly, you should have a look at the datename()
function in Books Online.
