title: The difference between 2 Instants in Calendar Days
body: <p>So I'm trying to get a specific number with my code. Right now I have:</p>
  
  <pre><code>Instant Today = 2018-07-17T13:45:00Z
  Instant Expiration1 = 2018-07-18T11:00:00Z
  long daysTilExp = Today.until(Expiration, Chronounit.DAYS)
  </code></pre>
  
  <p>The problem is that because this isn't exactly 24 hours apart it ends up returning <code>daysTilExp = 0</code> but I want <code>daysTilExp = 1</code> I'm trying to get that actual days apart the two Instants are so then even If I change the value of Expiration like so:</p>
  
  <pre><code>Instant Expiration1 = 2018-07-18T06:00:00Z
  </code></pre>
  
  <p>and now <code>daysTilExp = 2</code>. I looked at some other answers on StackOverflow but it doesn't look like people are using <code>Instant</code> and they aren't wanting the difference the same way</p>
