title: Google Sheet script to hide rows if date in column older than a week
body: <p>I'd like a script that hides rows if the date in column F is older than a week. I thought I found one but it hid the headers of the columns (row 2) as well which is no use.</p>
  
  <p>I don't want it to hide empty rows as they will be continuously updated. </p>
  
  <p>Many thanks.</p>
