There are two problems here.
First, you can only call getTime on an instance of the date. You need to wrap new Date in brackets or assign it to variable.

Second, you need to pass it a string in a proper format.

Working example:

<pre><code>(new Date("2012-02-26")).getTime();
</code></pre>

You need just to reverse your date digit and change <code>-</code> with <code>,</code>:
<pre><code>new Date(2012,01,26).getTime(); // 02 becomes 01 because getMonth() method returns the month (from 0 to 11)
</code></pre>
In your case:
<pre><code>var myDate=&quot;26-02-2012&quot;;
myDate=myDate.split(&quot;-&quot;);
new Date(parseInt(myDate[2], 10), parseInt(myDate[1], 10) - 1 , parseInt(myDate[0]), 10).getTime();
</code></pre>

Your string isn't in a format that the <code>Date</code> object is <a href="http://es5.github.com/#x15.9.1.15" rel="nofollow">specified to handle</a>. You'll have to parse it yourself, use a date parsing library like <a href="http://momentjs.com/" rel="nofollow">MomentJS</a> or the older (and not currently maintained, as far as I can tell) <a href="http://datejs.com" rel="nofollow">DateJS</a>, or massage it into the correct format (e.g., <code>2012-02-29</code>) before asking <code>Date</code> to parse it.

Why you're getting <code>NaN</code>: When you ask <code>new Date(...)</code> to handle an invalid string, it returns a <code>Date</code> object which is set to an invalid date (<code>new Date("29-02-2012").toString()</code> returns <code>"Invalid date"</code>). Calling <code>getTime()</code> on a date object in this state returns <code>NaN</code>.

Simply performing some arithmetic on a <code>Date</code> object will return the timestamp as a <code>number</code>. This is useful for compact notation. I find this is the easiest way to remember, as the method also works for converting numbers cast as <code>string</code> types back to <code>number</code> types.

It says NaN.. Can any one tell how to convert this?
