The 2nd argument to <code>moment()</code> is a <a href="http://momentjs.com/docs/#/parsing/string-format/">parsing format</a> rather than an display format.

For that, you want the <a href="http://momentjs.com/docs/#/displaying/format/"><code>.format()</code> method</a>:

<pre><code>moment(testDate).format('MM/DD/YYYY');
</code></pre>

Also note that case does matter. For Month, Day of Month, and Year, the format should be uppercase.

Include moment.js and using the below code you can format your date

var responseDate = moment(formatDate).format('DD/MM/YYYY');

My output is "13/05/2014"

May be this helps some one who are looking for multiple date formats one after the other by willingly or unexpectedly.
Please find the code:
I am using moment.js format function on a current date as (today is 29-06-2020)
var startDate = moment(new Date()).format('MM/DD/YY'); Result: 06/28/20
what happening is it retains only the year part :20 as &quot;06/28/20&quot;, after If I run the statement :
new Date(startDate)
The result is &quot;Mon Jun 28 1920 00:00:00 GMT+0530 (India Standard Time)&quot;,
Then, when I use another format on &quot;06/28/20&quot;: startDate = moment(startDate ).format('MM-DD-YYYY'); Result: 06-28-1920, in google chrome and firefox browsers it gives correct date on second attempt as: 06-28-2020. But in IE it is having issues, from this I understood we can apply one dateformat on the given date, If we want second date format, it should be apply on the fresh date not on the first date format result.
And also observe that for first time applying 'MM-DD-YYYY' and next 'MM-DD-YY' is working in IE.

You can pass &quot;L&quot; to <code>format</code> method, which handles internationalisation...
<pre><code>moment.locale('en-US');
moment().format(&quot;L&quot;);
&gt; &quot;06/23/2021&quot;

moment.locale('fr');
moment().format(&quot;L&quot;);
&gt; &quot;23/06/2021&quot;
</code></pre>
Other long date formats (<code>fr</code> locale):
<pre><code>LT : 'HH:mm',
LTS : 'HH:mm:ss',
L : 'DD/MM/YYYY',
LL : 'D MMMM YYYY',
LLL : 'D MMMM YYYY HH:mm',
LLLL : 'dddd D MMMM YYYY HH:mm'
</code></pre>

I have a string in this format:
<pre><code>var testDate = &quot;Fri Apr 12 2013 19:08:55 GMT-0500 (CDT)&quot;
</code></pre>
I would like to use <a href="https://momentjs.com/timezone/docs/" rel="noreferrer">Moment.js</a> get it in this format <code>mm/dd/yyyy : 04/12/2013</code> for display.
I tried to do it using this method,
<pre><code>moment(testDate,'mm/dd/yyyy');
</code></pre>
Which errors and says <code>there is no such method called replace</code>? Am I approaching this in the wrong way?
<hr />
<h3>Edit</h3>
I should also mention that I am using a pre-packaged version of Moment.js, packaged for Meteor.js
<pre><code>Object [object Date] has no method 'replace' : The Exact error from the console
