How to calculate Number of 'Working days' between two dates in Javascript using moment.js?

Question

How to calculate the number of working days between two dates in JavaScript using moment.js. I have a working formula that calculate these days, but the formula does not sat

Answer 1

I use a simple function to accomplish that. Maybe is not the most efficient but it works. It doesn't require Moment.js. it's just Javascript.

function getNumWorkDays(startDate, endDate) {
    var numWorkDays = 0;
    var currentDate = new Date(startDate);
    while (currentDate <= endDate) {
        // Skips Sunday and Saturday
        if (currentDate.getDay() !== 0 && currentDate.getDay() !== 6) {
            numWorkDays++;
        }
        currentDate = currentDate.addDays(1);
    }
    return numWorkDays;
}

To addDays, I use the following function:

Date.prototype.addDays = function (days) {
    var date = new Date(this.valueOf());
    date.setDate(date.getDate() + days);
    return date;
};
