dateformat

A node.js package for Steven Levithan's excellent dateFormat() function.

Modifications

• Removed the Date.prototype.format method. Sorry folks, but extending native prototypes is for suckers.
• Added a module.exports = dateFormat; statement at the bottom
• Added the placeholder N to get the ISO 8601 numeric representation of the day of the week

Installation

$ npm install dateformat
$ dateformat --help

Usage

As taken from Steven's post, modified to match the Modifications listed above:

var dateFormat = require('dateformat');
var now = new Date();

// Basic usage
dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM

// You can use one of several named masks
dateFormat(now, "isoDateTime");
// 2007-06-09T17:46:21

// ...Or add your own
dateFormat.masks.hammerTime = 'HH:MM! "Can\'t touch this!"';
dateFormat(now, "hammerTime");
// 17:46! Can't touch this!

// You can also provide the date as a string
dateFormat("Jun 9 2007", "fullDate");
// Saturday, June 9, 2007

// Note that if you don't include the mask argument,
// dateFormat.masks.default is used
dateFormat(now);
// Sat Jun 09 2007 17:46:21

// And if you don't include the date argument,
// the current date and time is used
dateFormat();
// Sat Jun 09 2007 17:46:22

// You can also skip the date argument (as long as your mask doesn't
// contain any numbers), in which case the current date/time is used
dateFormat("longTime");
// 5:46:22 PM EST

// And finally, you can convert local time to UTC time. Simply pass in
// true as an additional argument (no argument skipping allowed in this case):
dateFormat(now, "longTime", true);
// 10:46:21 PM UTC

// ...Or add the prefix "UTC:" or "GMT:" to your mask.
dateFormat(now, "UTC:h:MM:ss TT Z");
// 10:46:21 PM UTC

// You can also get the ISO 8601 week of the year:
dateFormat(now, "W");
// 42

// and also get the ISO 8601 numeric representation of the day of the week:
dateFormat(now,"N");
// 6

Localization

Day names, month names and the AM/PM indicators can be localized by passing an object with the necessary strings. For example:

var dateFormat = require('dateformat');
dateFormat.i18n = {
    dayNames: [
        'Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat',
        'Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'
    ],
    monthNames: [
        'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec',
        'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'
    ],
    timeNames: [
        'a', 'p', 'am', 'pm', 'A', 'P', 'AM', 'PM'
    ]
};

Notice that only one language is supported at a time and all strings must be present in the new value.

Breaking change in 2.1.0

• 2.1.0 was published with a breaking change, for those using localized strings.
• 2.2.0 has been published without the change, to keep packages refering to ^2.0.0 to continue working. This is now branch v2_2.
• 3.0.* contains the localized AM/PM change.
