Moment.js how to get week of month? (google calendar style)

Question

I am using Moment.js and it is great. The problem I have now is that I can\'t figure out how to get the week of the month a certain date is. I can only find \"week of year\"

Answer 1

function countWeekdayOccurrencesInMonth(date) {

    var m = moment(date),
            weekDay = m.day(),
            yearDay = m.dayOfYear(),
            count = 0;

    m.startOf('month');
    while (m.dayOfYear() <= yearDay) { 
        if (m.day() == weekDay) {
            count++; 
        }
        m.add('days', 1); 
    }

    return count;
}
