Date Range problem
Hi ,
I need a function that verfies the given date is between start date and end date .
I have written this but this not working if start date is 1900/01/01

Below is my code

Code:
validateDate()
{
        RC=$#
        if [ $RC -lt "3" ]
        then
                return 0
        else
                 #echo "Start Date is $START_DATE and End Date is $END_DATE"
                 dateComp2=`echo $START_DATE $fileDate | awk '$2<$1{print -1;next}{print ($2>$1)}'`
		# echo "$START_DATE ==== $fileDate ==== $dateComp2 "
                 if [ $dateComp2 -ne -1 ]
                 then
			dateComp3=`echo $fileDate $END_DATE | awk '$2<$1{print -1;next}{print ($2>$1)}'`
			if [ $dateComp3 -ne -1 ]
			then
				return 1
			else 
				return 0
			fi
                 else 
			return 0
		 fi
		 
        fi

}

START_DATE=$1
fileDate=$2
END_DATE=$3
validateDate $1 $2 $3 
if [ $? -eq 1 ]
then
	echo "present "	
elif [ $? -eq 0 ]
then
	echo "not present "
fi

the above code is not working for
sh dateValidation.sh 1900/01/01 2009/07/15 2009/07/14

please suggest any modification or alternate function?
