body: <p>Currently in my build i am using 
  dynamic parameter (<a href="https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+Dynamic+Parameter+Plug-in" rel="nofollow">https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+Dynamic+Parameter+Plug-in</a>) to get current date and time. I use this variable and set it part of my build process.</p>
  
  <p>How to get next weeks date for wednesday?
  For example: currently todays date is 10/14/2014. Next week wednesday date is 10/19/2014.</p>
  
  <p>I cannot seem to find any other plugins or scripts that does this.</p>
