title: When searching Issues or Pull Requests in Github, can you specify a date relative to "today"?
body: <p><strong>Is there a way to search Pull Requests (and likewise Issues) on Github where you specify a date range relative to today?</strong></p>
  
  <p>My team meets weekly with another team, and we like to present them a list of Github pull requests we've merged within the past week.</p>
  
  <p>We can do a search for any items merged since a particular date with the filter:</p>
  
  <p><code>is:pr is:closed merged:&gt;=2016-03-31</code></p>
  
  <p>But this needs to be updated every week, which is less than ideal. (As you can see, it's already out of date :)</p>
  
  <p>However I see no mention of relative dates in their support article on searching issues:

  <p>Nor is there mention of relative dates in the search syntax article:
