you can try using isDate() from Underscore JS library.

Link to source: http://underscorejs.org/#isDate

Something like this:

var is_date = _.isDate(myDate);

The easiest thing to do is use the moment.js library. It's great for a number of things when manipulating dates. Works in the browser and in node.js.

This code is working for me...........Thanks for responses

 function checkEnteredDates(stdateval, endateval) {

        var beginDt = new Date(stdateval);
        var endDt = new Date(endateval);

        if (beginDt > endDt) {
            return true;

One thing to point out is that if your beginDt is less than or equal to your endDt, which is the case most of the time, then you will get false when you should be getting true. Assuming that you're checking that stdateval and endateval are valid dates. – SpartaSixZero May 26 '15 at 20:01
