Validating month value in shell script

Hi,

the below script is to get & check the correct values for minutes (0-59) that is inputed by user :

Code:
printf "$FBOLD\nPlease enter the minutes (0-59): $FREG"
        read MIN

        case "$MIN" in
        [0-9]|[0-5][0-9]) break 2;;
          *) 
        echo ""
     echo "Invalid minutes, please try again.";;
        esac

How to give the same range for day of month (1-31) and for month (1-12) and hour (0-23) ???

Also, after getting user input, how to get it displayed as below :

Cronjob scheduled on "month day_of_month day_of_week hour minute "

With Regards

A summary of options is included below. -B PIXMAP, --background=PIXMAP Use the given pixmap as the clock background (size must be 64x64). -H COLOR, --hands-color=COLOR Draw the hands (hour, minute and second) in the specified color. -S COLOR, --second-hand-color Draw the second hand in the specified color -h, --help Show summary of options. --hour-hand-length=INT Draw the hour hand with the specified length of INT. --minute-hand-length=INT Draw the minute hand with the specified length of INT. --second-hand-length=INT Draw the second hand with the specified length of INT. --second-hand-width=INT Draw the minute hand with the specified width of INT. -s, --second-hand Don't display the second hand. -v, --version Show version of program. -w, --withdrawn Don't start up in a withdrawn (iconic) state.
