Today we were playing with a very useful library for Date handling in javascript called Moment.js. As his description says, Moment.js is a library for Parse, validate, manipulate, and display dates in JavaScript.

From a simple string, with some valid date format, it will create an object (parse), will validate the string and we can add or delete time, reformat the date and do many more manipulations of the date object in order to do a better display of the information.

Instead of modifying the native


, Moment.js creates a wrapper for the


object. To get this wrapper object, simply call


with one of the supported input types.



prototype is exposed through


. If you want to add your own functions, that is where you would put them.

To use it you just need to remember this function


To get the current date and time, just call


with no parameters.

<span class="keyword">var</span> now = moment();

This is essentially the same as calling

moment(new Date()).

If you want to parse a string you must use it


When creating a moment from a string, we first check if the string matches known ISO 8601 formats, then fall back to

new Date(string)

if a known format is not found.

If you have a PHP timstamp you can parse it with Moment.js but before do it multiply the timestamp by 1000 since in JavaScript the timestamp are in milliseconds and in PHP in seconds.

You can find more information about the usage in the library docs.
