Solution

Despite its name, the forfiles command is able to handle both files and folders. Here's a batch script that does the job:

@echo off
setlocal

set target=X:\backups
set days=-2

for /f "usebackq delims=" %%G in (
`forfiles /p "%target%" /c "cmd /c if /i @isdir == true echo @path" /d %days% 2^>nul`
) do echo rd /s /q "%%~G"

pause
endlocal & exit /b

How it works

First of all, the target and days variables are initialized. The first one is set to the folder you want to scan, and the latter is the amount of days. Negative values mean older than or equal.

The forfiles command is then run by specifying the folder and number of days that were set earlier. For each result, the special @isdir variable is checked: if the value is true the current entry is a folder, and its @path is echoed. The command output is then parsed to get all matching folders and delete them. For safety reasons, there's an extra echo command so you can check whether the right folders are removed.

When using the recursive switch (/s), all files, folders, and their subfolders are processed. In this case you don't want to; otherwise you might end up deleting old subfolders contained in newer folders, which shouldn't be touched at all.
