[DATE] Pattern matching notation

Hello,
I want to verify the format date like 2013-03-08 (YYYY-MM-DD)
It doesn't work because the pattern matching notation below returns false while the date is right.
Can you help me ? Thanks in advance

Code:
case "$6" in ([1-9][0-9][0-9][0-9]-0[1-9]-0[1-9] | [1-9][0-9][0-9][0-9]-1[0-2]-1[0-9] | [1-9][0-9][0-9][0-9]-1[0-2]-2[0-9] | [1-9][0-9][0-9][0-9]-1[0-2]-3[0-1]) 
# Nothing, OK ! 
    ;; 
(*)   echo 'Fatal, $6 eq '"'$6'"', Right format is YYYY-MM-DD' >&2 
    ;; 
esac
