<p>If you want to check if <em>current</em> time is in range then the <em>range</em> should be DATE + TIME as current time is DATE + TIME</p>

<h1>Possible solution</h1>

<p>You can convert all three datetimes to moment instances and just use </p>

<pre><code>start.isBefore(current)
&amp;&amp; current.isBefore(end)
</code></pre>

  <p><strong>"I'm not sure how to check if the current date is within a range in the array."</strong></p>
</blockquote>

<p>You'd loop through the array and compare. I'd suggest storing the ranges as an array of objects where each individual range is something like <code>{start: "10:15", end: "10:45"}</code>.</p>

<p>JavaScript doesn't have time objects, only <code>Date</code> that includes date and time information. So I think it would be easiest to convert the current time to the "hh:mm" format as a string and then just do simple string compares against your range values, rather than worrying about converting the range values to date objects. So:</p>

<pre><code>var timeRanges = [
  { start: "06:00", stop: "06:30" },
  { start: "12:30", stop: "13:00" },
  { start: "23:45", stop: "00:15" }
]

function isTimeInRange(time) {
  for (var i = 0; i &lt; timeRanges.length; i++) {
    var range = timeRanges[i]
    if ((time &gt; range.start &amp;&amp; time &lt; range.stop)
      || (range.start &gt; range.stop &amp;&amp; (time &gt; range.start || time &lt; range.stop))) {
      return true
    }
  }
  return false
}
</code></pre>

<p>But you can make the code neater, and shorter, using the <a href="https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/some?v=control" rel="nofollow noreferrer">array <code>.some()</code> method</a>, with or without <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions" rel="nofollow noreferrer">arrow functions</a>:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var timeRanges = [
  { start: "06:00", stop: "06:30" },
  { start: "12:30", stop: "13:00" },
  { start: "23:45", stop: "00:15" }
]

function isTimeInRange(time) {
  return timeRanges.some(range =&gt;
    (time &gt; range.start &amp;&amp; time &lt; range.stop)
    || (range.start &gt; range.stop &amp;&amp; (time &gt; range.start || time &lt; range.stop))
  )
}

function pad(d) {
  return ("0" + d).slice(-2)
}

function getCurrentTime() {
  var now = new Date()
  return pad(now.getHours()) + ":" + pad(now.getMinutes())
}

console.log("Current time in range? " + isTimeInRange(getCurrentTime()))
// test some other times
console.log(isTimeInRange("06:15")) // true
console.log(isTimeInRange("12:35")) // true
console.log(isTimeInRange("13:30")) // false
console.log(isTimeInRange("23:50")) // true
console.log(isTimeInRange("00:14")) // true</code></pre>
</div>
</div>
</p>

<p>Obviously you can change <code>&lt;</code> and <code>&gt;</code> to <code>&lt;=</code> and <code>&gt;=</code> if desired.</p>

<p>For a website blocking/productivity app written in javascript, I'd like to have a user input a series of time ranges available for free time (in his local time). Example:</p>

<p>06:00-06:30</p>

<p>12:30-13:00</p>

<p>23:45-00:15</p>

<p>24 format is not required (I'm just assuming it will be easier)</p>

<p>The program should then check the specified free time ranges against the current time to determine whether block mode is on or off.</p>

<p>My rough idea is to use an inbuilt Javascript function to grab the current DateTime, and convert it to 24 hour format if necessary. I think the time ranges will be in an array. I'm not sure how to check if the current date is within a range in the array.</p>

<p>The logic must also be able to handle the crossover from 23:00 to 0:00.</p>

<p>Anyways that is my line of thought. Thanks for any suggestions including ones that take a different path.</p>
