I have a date string which looks like this:

Thu Feb 09 2012 01:50:00 GMT+0000 (GMT Standard Time)

And I basically need to re-format it to be 2 strings (one for date and one for time).

The date format needs to be:

m-d-Y (01-16-2012)

and the time should be

H:i (10:30)

• javascript
• ajax
• date
• format

• My "H:i" and "m-d-Y" are from PHP, I didn't know the correct ones in JS. Sorry. – DarkMantis Commented Jan 16, 2012 at 16:25

I would remend you take a look at Datejs. It is an excellent JavaScript library for parsing dates. (Making use of jQuery for cleanliness)

<script type="text/javascript" src="http://www.datejs./build/date.js"></script>
<script type="text/javascript" src="https://ajax.googleapis./ajax/libs/jquery/1.7.1/jquery.min.js"></script>

<div id="date"></div>
<div id="time"></div>
<script type="text/javascript">
var d = "Thu Feb 09 2012 01:50:00 GMT+0000";
var dout = Date.parse(d);
$("#date").text(dout.toString('M-d-yyyy')); 
$("#time").text(dout.toString('HH:mm'));     
</script>

You might want to take a look at Moment.js

I believe DateJS extends the native JavaScript Date Object and might not be what you want. I am pretty sure MomentJS ( is was inspired by DateJS ) does not extend the native Date Object.

Check out the docs for Moment.js, this should do the trick for you: http://momentjs./docs/#/parsing/string+format

var foo = moment( stringDateValue , 'MM-DD-YYYY hh:mm');

I'm not sure about the built-in Date object, but Datejs can do this.

Using Datejs' toString method:

var now = new Date();
console.log(now.toString('MM-dd-yyyy')); // 01-16-2012
console.log(now.toString('HH:mm')); // 10:30

DEMO: http://jsfiddle/b3wgR/3

EDIT: If your date is from a string, Datejs can parse it for you.

var str = "Thu Feb 09 2012 01:50:00 GMT+0000";
var date = Date.parse(str);
console.log(date.toString('MM-dd-yyyy')); // 02-09-2012
console.log(date.toString('HH:mm')); // 01:50

DEMO: http://jsfiddle/RY5jb/

    var td = new Date();
    var weekday = new Array(7);
    weekday[0] = "Sunday";
    weekday[1] = "Monday";
    weekday[2] = "Tuesday";
    weekday[3] = "Wednesday";
    weekday[4] = "Thursday";
    weekday[5] = "Friday";
    weekday[6] = "Saturday";

    var month_name = new Array(12);
    month_name[0] = "January";
    month_name[1] = "February";
    month_name[2] = "March";
    month_name[3] = "April";
    month_name[4] = "May";
    month_name[5] = "June";
    month_name[6] = "July";
    month_name[7] = "August";
    month_name[8] = "September";
    month_name[9] = "October";
    month_name[10] = "November";
    month_name[11] = "December"; 

   document.getElementById("TodayDate").innerHTML = weekday[td.getDay()] + ", " + month_name[td.getMonth()] + " " + td.getDate() + ", " + td.getFullYear();

Now output is like : Thursday, May 22, 2014

here is a polyfill for new Date().format("MM-DD-YYYY HH:mm");

it will return a string with whatever format you want

//example: dateFormater("D, M n, Y h:ft", new Date(), 2)
//results: a formated date two days from now -> Sunday, February 10, 2013 3:07pm
//today is Friday 2/8/13

    var moddt = "";
    var tmp;
    
    //add days to date (use -1 to subtract days
