Batch command - adding date at the end of folder - date

Question

I currently run a batch command to create a folder 1 day in advanced and label it as MMDDYY.
Everything is working as intended except single digit days. Currently it named the next day folder has 12214, is it possible to have it name it as 120214?
#echo off
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%"
set "YYYY=%dt:~0,4%"
set "MM=%dt:~4,2%"
set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%"
set "Min=%dt:~10,2%"
set "Sec=%dt:~12,2%"
:loop
set /a DD+=1
if %DD% gtr 31 (
set DD=1
set /a MM+=1
if %MM% gtr 12 (
set MM=1
set /a YY+=1
set /a YYYY+=1
)
)
xcopy /d:%MM%-%DD%-%YYYY% /l . .. >nul 2>&1 || goto loop
echo %DD%/%MM%/%YYYY%
mkdir "C:\Users\Name\Desktop\%mm%%dd%%yy%\"
pause

You need to pad again the data once the operations have been done. Also you will need some more logic to handle the month change
#echo off
setlocal enableextensions disabledelayedexpansion
rem Retrieve data
for /f "tokens=2 delims==" %%a in ('wmic OS Get localdatetime /value') do set "dt=%%a"
set "YY=%dt:~2,2%"
set "YYYY=%dt:~0,4%"
set "MM=%dt:~4,2%"
set "DD=%dt:~6,2%"
set "HH=%dt:~8,2%"
set "Min=%dt:~10,2%"
set "Sec=%dt:~12,2%"
rem Remove padding from date elements and increase day
set /a "y=%YYYY%", "m=100%MM% %% 100", "d=(100%DD% %% 100)+1"
rem Calculate month length
set /a "ml=30+((m+m/8) %% 2)" & if %m% equ 2 set /a "ml=ml-2+(3-y %% 4)/3-(99-y %% 100)/99+(399-y %% 400)/399"
rem Adjust day / month / year for tomorrow date
if %d% gtr %ml% set /a "d=1", "m=(m %% 12)+1", "y+=(%m%/12)"
rem Pad date elements and translate again to original variables
set /a "m+=100", "d+=100"
set "YYYY=%y%"
set "YY=%y:~-2%"
set "MM=%m:~-2%"
set "DD=%d:~-2%"
echo Tomorrow: %YYYY% / %MM% / %DD%
Just add the folder creation in the required format

Batch is cumbersome with date math. Leap years, month / year changes / etc can be a pain to deal with. I suggest using a JScript Date() object, where all such conversions are handled automatically.
As follows is a batch / JScript hybrid script. Save it with a .bat extension and run it as you are used to running your typical batch scripts.
#if (#a==#b) #end /* JScript ignores this multiline comment
:: batch portion
#echo off
setlocal
for /f "tokens=1-3" %%I in ('cscript /nologo /e:JScript "%~f0"') do (
set "MM=%%I"
set "DD=%%J"
set "YYYY=%%K"
)
xcopy /d:%MM%-%DD%-%YYYY% /l . .. >nul 2>&1 || goto loop
echo %MM%/%DD%/%YYYY%
mkdir "%userprofile%\Desktop\%MM%%DD%%YYYY:~-2%\"
pause
goto :EOF
:: end batch portion / begin JScript */
function zeroPad(what) { return (what+'').length < 2 ? '0'+what : what; }
var tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate() + 1);
WSH.Echo([
zeroPad(tomorrow.getMonth() + 1),
zeroPad(tomorrow.getDate()),
tomorrow.getFullYear()
].join(' '));
