<p>You are using dString in your loop. It's not a date, it's a string. </p>

<p>Also, I would avoid using the <code>Date(string)</code> constructor. I would use <code>Date(year, month, date)</code> instead. Careful though, january is the month 0 so you'll have to retract 1 to the month obtained by splitting the string. </p>

<p>See the snippet below for a working example. </p>

<div class="snippet-code">

    var in30DaysDate = new Date(startParts[2], startParts[1]-1, startParts[0]);; 

    in30DaysDate.setDate(startDate.getDate() + 30)

    console.log("Start:" + startDate + " EndDate: " + in30DaysDate);

<p>I'm trying to <code>console.log</code> all the dates between two dates.</p>

<p>Here is the code i have so far:</p>

<pre><code>    var dString = "18.04.2018";
    var dParts = dString.split('.');
    var in30Days = new Date(dParts[2] + '/' +
                            dParts[1] + '/' +
                            (+dParts[0] + 10)
                   );
    var endDate =  in30Days.getDate() + "." + (in30Days.getMonth()+1) + "." +in30Days.getFullYear();     
    console.log("Now:" + dString + " EndDate: " + endDate);

    for (var d = dString; d &lt;= endDate; d.setDate(d.getDate() + 1)) {
        var loopDay = new Date(d);
        console.log("Day:" + loopDay);
    }
</code></pre>

<p>The end date is the start date plus 10 days.</p>

<p>Here is the console log output i receive:</p>

<pre><code>Now:18.04.2018 EndDate: 28.4.2018
Day:Invalid Date
</code></pre>

<p>Why the date is invalid. Where is my mistake ?</p>
