title: How to get a cronjob to execute 3 days, and 2 days break?
body: <p>I want a script to execute 3 days in a row, and then 2 days not, and then 3 days again.
  I think this does it, but I'm not sure.</p>
  <blockquote>
  <p>00 22 1-31/5,2-31/5,3-31/5 * *</p>
  </blockquote>
  <p>How the first 10 days (2 loop) would look:</p>
  <p>01/01/2021  On</p>
  <p>01/02/2021  On</p>
  <p>01/03/2021  On</p>
  <p>01/04/2021  Off</p>
  <p>01/05/2021  Off</p>
  <p>01/06/2021  On</p>
  <p>01/07/2021  On</p>
  <p>01/08/2021  On</p>
  <p>01/09/2021  Off</p>
  <p>01/10/2021  Off</p>
