title: only do if day... batch file
body: <p>hello i got a batch file, something like this:</p>
  
  <pre><code>if %day%==monday, tuesday, wednesday, thursday, friday (
  goto yes
  ) else (
  goto no
  )
  </code></pre>
  
  <p>Now i know the first line won't work.</p>
  
  <p>What i actually want to happen:</p>
  
  <p>It automatticly checks which day it is. If it is Monday to Friday, it has to go to 'yes', otherwise (saturday/sunday) to 'no'.</p>
  
  <p>How to do this?</p>
