title: Show current week/date on Excel Project Timeline
body: <p>I have Excel based Project Planner which I am working on.
  <a href="https://i.stack.imgur.com/h9QYp.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/h9QYp.png" alt="It looks like that"></a></p>
  
  <p>It is downloaded from some free templates and I am modyfying it to get it fit to our needs.</p>
  
  <p>I need to show somehow - border, pattern overlay etc. - current week.
  It is not an issue for me to get current week number,
  but I have no idea how to find this week in this table and how to highlight it.</p>
  
  <p>Can anybody help ?</p>
