I'm very new to javascript and moment.js. I'm working on a site where we need to list out the next 5 possible pickup dates for a product, excluding weekends and holidays. I have a start on this, using a function I found online. It works well at skipping the weekends, however I can't get the holidays working. Any help would be appreciated. /
moment.fn.addWorkdays = function(days) {
var increment = days / Math.abs(days);
var date = this.clone().add(Math.floor(Math.abs(days) / 5) * 7 * increment, 'days');
var remaining = days % 5;
while (remaining != 0) {
date.add(increment, 'days');
// Check for weekends and a static date
if (!(date.isoWeekday() === 6) && !(date.isoWeekday() === 7) && !(date.date() === 1 && date.month() === 4)) {
remaining -= increment;
}
}
return date;
};
for (count = 0; count < 5; count++) {
var test = moment().addWorkdays(count + 1).format('dddd, MMMM Do YYYY');
document.write("Pickup date : " + test);
document.write("<br />");
}

Reset to default 4Here's a quick and easy solution using my moment-holiday plugin. :)
function getNextWorkDays(count, format) {
if (!count) { count = 5; }
if (!format) { format = 'dddd, MMMM Do YYYY'; }
var days = [];
var d = moment().startOf('day');
for (i = 0; i < count; i++) {
d.add(1, 'day');
if (d.day() === 0 || d.day() === 6 || d.isHoliday()) {
count++;
continue;
}
days.push(moment(d).format(format));
}
return days;
}
var days = getNextWorkDays();
alert("The following days are available for pickup:\n\n" + days.join("\n"));

I know this is an old post, but now that moment is deprecated using built-in date methods is a much better approach. Here is a gist I created doing just that and is copied below for reference.
function isHoliday(date: Date) {
const holidays = {
MD: {
// Month, Day
'1/1': "New Year's Day",
'7/4': 'Independence Day',
'11/11': "Veteran's Day",
'12/25': 'Christmas Day',
'12/31': "New Year's Eve"
},
MODW: {
// Month, Occurence, Day of Week
'1/3/1': 'Martin Luther King Jr. Day',
'2/3/1': 'Presidents Day',
'5/L/1': 'Memorial Day',
'9/1/1': 'Labor Day',
'10/2/1': 'Columbus Day',
'11/4/4': 'Thanksgiving Day'
}
};
const dayOfTheMonth = date.getDate();
const month = date.getMonth() + 1;
const dayOfTheWeek = date.getDay(); // 0 - 6, Su -> Sa
const lastDayOfTheMonth = new Date(date.getFullYear(), date.getMonth() + 1, 0).getDate();
const isLastOccurrence = dayOfTheMonth + 7 > lastDayOfTheMonth;
let currentOccurrenceDay = dayOfTheMonth,
occurrence = 0;
for (currentOccurrenceDay; currentOccurrenceDay > 0; currentOccurrenceDay -= 7) occurrence++;
return !!(
holidays.MD?.[`${month}/${dayOfTheMonth}`] ||
(isLastOccurrence && holidays.MODW?.[`${month}/L/${dayOfTheWeek}`]) ||
holidays.MODW?.[`${month}/${occurrence}/${dayOfTheWeek}`]
);
}
