Zip a folder older than XX days and then delete it

How can I do a batch file for zip the folder older than an amount of days, with name: nameoffolder.zip and then delete it?

I tried with this code, but it doesn't work well:

@echo off
setlocal EnableExtensions DisableDelayedExpansion

rem // Define constants here:
set "_ROOT=C:\Report"
set "_PATTERN=*.*"
set "_LIST=%TEMP%\%~n0.tmp"
set "_ARCHIVER=%ProgramFiles%\7-Zip\7z.exe"

rem // Get current date in locale-independent format:
for /F "tokens=2 delims==" %%D in ('wmic OS get LocalDateTime /VALUE') do             
set "TDATE=%%D"
set "TDATE=%TDATE:~,8%"

pause
rem // Create a list file containing all files to move to the archive:
> "%_LIST%" (
    for /F "delims=" %%F in ('
        forfiles /S /P "%_ROOT%" /M "%_PATTERN%" /D -7 /C "cmd /C echo @path"
    ') do echo(%%~F
) && (
    rem // Archive all listed files at once and delete the processed files 
    finally:
    "%_ARCHIVER%" a -sdel "%_ROOT%_%TDATE%.zip" @"%_LIST%"
    rem // Delete the list file:
    del "%_LIST%"
)

endlocal
pause
exit /B
