Bash script accepting variables in valid number format
Hi Experts
I would like to ask if there is a way to validate if the variable passed is in this kind of sample format "06-10" or "10-01". It was really a challenge to me on how to start and echnically the "6-10" stands for "June 10" and "10-01" stands as "October 1", overall it needs to have like of a "Month-Day" valid in number format. I would like to have an if-then statement that would validate if the variables passed are in correct, something like these:

Code:
#!/bin/bash 
# This script will ONLY accept two parameters in number format  
# according to "MM-DD" which is "XX-XX"  # To run this script: ./script.sh xx-xx xx-xx 
DATE1=$1 
DATE2=$2
 if [DATE1 is in correct format] && [DATE2 is in correct format]  
   then   
     echo "Correct format"   
     echo "DATE1 = $DATE1"   
     echo "DATE2 = $DATE2"  
   else   
     echo "Not correct format"    
    exit 1 
  fi
