title: DAX: Calculate Start Dates Based on Duration & Order
body: <p>I have a table that I am trying to convert into a gantt chart. This table contains the task order (sometimes the same for those in parallel), as well as a task duration (by quarter).</p>
  
  <p>If I have a Project Start Date = 1/1/2020, how could I calculate the Start &amp; End dates for each subsequent task?</p>
  
  <p>Example,</p>
  
  <pre><code>Task A: Order = 1, Duration = 4 ---&gt; Start = 1/1/2020, End = 1/1/2021
  Task B: Order = 2, Duration = 1 ---&gt; Start = 1/1/2021, End = 3/1/2021
  Task C: Order = 3, Duration = 2 ---&gt; Start = 3/1/2021, End = 9/1/2021
  </code></pre>
