Date Validation not working

Hi Experts,

I have a date validation script in that i will validate the date for a given format and search in the logs for that date. The script logic is very simple like below.


Code:
Validate_Date()
{
is_valid=1
while [ $is_valid -ne 0 ]
do
 date_format=$(date "+$1")
 echo -e "Please enter the $2 date like - \033[0;32m$date_format\033[0;37m"
 read MY_DATE
 tmp=$(date "+$1" -d "$MY_DATE" 2>&1)
 if [ "${tmp:6:7}" == "invalid" ]; then
  is_valid=1
  echo -e "Invalid date $tmp"
 else
  MY_DATE=$tmp
  is_valid=0
 fi
done
}


This is working fine for almost all date format expect the below one

Code:
%d/%m/%Y

Whenever I pass some inputs which is valid its throwing error

Code:
$Validate_Date "%d/%m/%Y"
Please enter the  date like - 02/06/2014
25/05/2014
Invalid date date: invalid date `25/05/2014'
Please enter the  date like - 02/06/2014

The reason is server is always taking MMDDYYYY indeed of DDMMYYYY.

Code:
$date -d "30/06/2014" "+%d/%m/%Y"
date: invalid date `30/06/2014'
$date -d "25/05/2014" "+%d/%m/%Y"
date: invalid date `25/05/2014'


How to resolve this.

Thanks
Senthil
