Answer 1

I made a function :getdate who test the date try it; It will test if the separators are correct, the value range for thr month and the day and if the values are NUM.

@ECHO OFF
setlocal enabledelayedexpansion

:GetDate
set /p $D=Enter a date (MM-DD-YYYY) :

set $separate=%$d:~2,1% %$d:~5,1%

for %%a in (%$separate%) do (if "%%a" neq "-" (echo Wrong Separator : %%a
                                               pause
                                               goto:Getdate))


set $D=%$D:-= %
set $c=1

for %%a in (%$d%) do (call:test !$c! %%a
                      set /a $c+=1)

if !$c!==4 set $DateOK=%$month%-%$day%-%$Year%
echo This DATE IS OK %$dateOK%
exit /b

:test
if %1 equ 1 (echo %2 | findstr [0-9][0-9]
             if errorlevel 1 (echo Unvalid value for Month [NOT NUM]: %2
                              pause
                              goto:getdate)

             if %2 GTR 12 (echo Unvalid value for Month [VALUR RANGE +]: %2
                                pause
                                goto:getdate)
              if %2 LSS 1 (echo Unvalid value for Month [VALUR RANGE -]: %2
                                pause
                                goto:getdate)
              set $month=%2) 



if %1==2  (echo %2 | findstr [0-9][0-9]
           if errorlevel 1 (echo Unvalid value for Day [NOT NUM]: %2
                            pause
                            goto:getdate)
           if %2 GTR 31 (echo Unvalid value for Day [VALUR RANGE +] : %2
                              pause
                              goto:getdate)
           if %2 LSS 01 (echo Unvalid value for Day [VALUE RANGE -]: %2
                              pause
                              goto:getdate)
           set $day=%2)


if %1==3  (echo %2 | findstr [0-9][0-9][0-9][0-9]
           if errorlevel 1 (echo Unvalid value for Year [NOT NUM] : %2
                            pause
                            goto:getdate)
         set $Year=%2)
