title: Google script trigger weekdays only
body: <p>I have a tool that I have created with Google docs, part of it is that I back up a set of numbers on a daily basis at 11am which I use to create a chart to show progress over time. I have this script running using a trigger that is set to backup the data once a week.</p>
  
  <p>What I would really like to do is only back this data up on weekdays as the weekend data is throwing my averages out. So just Monday - Friday daily at 11am</p>
  
  <p>Does anyone have a way of doing setting the script to run this way programatically?</p>
