From user KBA (https://stackoverflow.com/users/453331/kba) from response How do I calculate number of given weekday between range using Moment JS?:

var firstDate = new Date("March 1, 2015");
var secondDate = new Date("March 25, 2015");

function getWeekdaysBetweenDates(firstDate, secondDate, dayOfWeek) {
    var MILISECONDS_IN_DAY = 86400000;

    function getNextDayOfWeek(date, dayOfWeek) {
        date.setDate(date.getDate() + (7 + dayOfWeek - date.getDay()) % 7);
        return date;
    }

    firstDate = getNextDayOfWeek(firstDate, dayOfWeek);
    if (firstDate > secondDate) {
        return 0;
    }

    return 1 + Math.floor(((secondDate - firstDate) / MILISECONDS_IN_DAY) / 7);
}
