I currently have a date which is formatted in PHP like this date('D d F g:i A Y', $l2['available']) which outputs a date in this format: Tue 15 May 5:45 PM 2012

I want to achieve this same format in Javascript/jQuery.

So far I've done this:

var lessonTime = new Date(data.lessons[i].available * 1000);
lessonTime.toDateString();  

which results in the date below:

Thu Mar 22 2012

Is there a way to control the format like you can with PHP date function?

I wrote moment.js and it's pretty good at date manipulation and formatting.

moment().format('ddd D MMM h:mm A YYYY');

It's also faster and smaller than Date.js and doesn't modify the Date.prototype which is generally considered unsafe.

There's very little native date formatting in JavaScript, nothing parable to the PHP formatting capabilities. There are a few libraries that can help with this:

• Date.js extends Date.toString() to accept formatting parameters

• jQuery has a dateFormat plugin

• D3.js has time-formatting support - even if you don't use the whole library, you could probably use the time formatter by itself.

var now = new Date();
dateFormat(now, "ddd dd mmm h:MM TT yyyy");
