npm install moment-isocalendar

If you are looking for a Python-like isocalendar method, you can use Rocky Meza's plugin


Calling the isocalendar method on a moment will return an array like the following:

[year, week_of_year, day_of_week, minutes_since_midnight]

moment().isocalendar(); // [2012, 8, 5, 870]

You can also reconstruct a moment from a isocalendar array.

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