You could parse the date like this

Code:
$ cat compare_dates.ksh
#!/bin/ksh

USERDATE="2/15/2012"
IFS=/
set -- $USERDATE
typeset -Z2 MONTH=$1
typeset -Z2 DAY=$2
YEAR=$3
MYDATE="$YEAR$MONTH$DAY"
echo $MYDATE

TODAY=$(date +%Y%m%d)

if [ $TODAY -eq $MYDATE ]; then
     echo "We have a match!"
fi

exit 0

$ ./compare_dates.ksh
20120215
We have a match!
