moment.isocalendar.js

This plugin provides a Python-like isocalendar method to moment objects.

How to use?

Simply call the isocalendar method on any moment object. It returns an array of four items: year, week_of_year, day_of_week, minutes_since_midnight.

moment(new Date(2011, 11, 23, 14, 30)).isocalendar();
// [2011, 51, 5, 870]

Additionally, there is a function that provides the inverse functionality, it takes an isocalendar array and returns a moment object.

moment.fromIsocalendar([2011, 51, 5, 870]).format('LLLL');
// "Friday, December 23 2011 2:30 PM"

Getters and Setters

This plugin additionally provides getters and setters for the ISO representation values.

var m = moment([2012, 3, 8]); // Sunday, 2012 April 8th

m.isoday(); // 7
m.isoweek(); // 14

m.isoday(6).format('YYYY-MM-DD'); // "2012-04-07"
