Changing Date format in JavaScript

Question

var dt="29/05/2013"; //DD/MM/YYYY

I want to convert to yyyy/MM/dd format;

The approach I've used is:

var newdate=dt.getFullYear()+"/"+dt.getMonth()+"/"+dt.getDate();

Is there any simple approach to convert it with out using substring?

I don't want to use plugins by the way...

You don't need `Date` object, it's purely string manipulation. — Ja͢ck, May 29 '13 at 06:54

Consider using a library to help you: http://www.datejs.com/ and http://momentjs.com/ are good libraries.

Date.parse ("29/05/2013").toString("yyyy/MM/dd")

simply try like this

var a = dt.split("/");
var new_date = a[2]+'/'+a[1]+'/'+a[0];
alert(new_date);

The edit would work; what surprises me is that you managed to get +3 on a bogus answer before =/ – Ja͢ck May 29 '13 at 06:56
I had to double check that original code, I thought I had missed something in JS! – jammykam May 29 '13 at 06:57

That's crap! `Date` constructor only supports iso8601 reliably and `Date.toString()` doesn't use a date format argument; no matter now, but still good to remember. – Ja͢ck May 29 '13 at 06:59
@Gautam3164 Yupp it will work but yours doesn't ... Anyway cool buddy ...!!! – Prasath K May 29 '13 at 06:59

The fact that it worked for you before is probably because you were using date.js. – Ja͢ck May 29 '13 at 07:11
yah @Jack you are right and we are here to help only,and may be its my mistake bec i didnt used .parse of my date for the previuos ans,after I have seen jammaykam ans I see i forgotted – GautamD31 May 29 '13 at 07:13

If you are using jquery ui..

var newdate = $.datepicker.formatDate('yy/mm/dd', new Date());

Look this Example:

    var d = new Date ( "January 6, 1972" );

    var curr_date = d.getDate();
    var curr_month = d.getMonth() + 1; //Months are zero based
    var curr_year = d.getFullYear();
    document.write(curr_date + "-" + curr_month + "-" + curr_year);

Hope it will help you!
