title: How to get Current Date - 1, -2 ,-3 , -4 in Batch
body: <p>This is what i would like to do:</p>
  
  <ol>
  <li>Get Current Date,  which is easy --- %DATE%</li>
  <li>DO Current Date - 1, which i cant seem to get as i have tried different options.</li>
  </ol>
  
  <p>I would like to get last 4 dates from the current date and then store them in 4 different variables. Then Convert each of these date into YYYYMMDD format.</p>
  
  <p>So %DATE% gives me 06/04/2016.....
  %DATE%</p>
  
  <pre><code>-1 should give me 05/04/2016 stored in Variable say Date1........
  -2 should give me 04/04/2016 stored in Variable say Date2........
  -3 should give me 03/04/2016 stored in Variable say Date3........
  -4 should give me 02/04/2016 stored in Variable say Date4........ 
  </code></pre>
  
  <p>then i would like to convert value stored in each of these variables into YYYYMMDD</p>
  
  <p>For ex: </p>
  
  <pre><code>05/04/2016 to 20160405 ....
  04/04/2016 to 20160404 ....
  03/04/2016 to 20160403 ....
  02/04/2016 to 20160402 ....
  </code></pre>
