Answer 1

Here is a solution using moment.js:

function getAmountOfWeekDaysInMonth(date, weekday){
    date.date(1);
    var dif = (7 + (weekday - date.weekday()))%7+1;
    console.log("weekday: "+ weekday +", FirstOfMonth: "+ date.weekday() +", dif: "+dif);
    return Math.floor((date.daysInMonth()-dif) / 7)+1;
}

The argument date has to be any date in the month you want analyse.
