How to count “+1” when a specific date occurs

Hello everyone!

I have this code through which I show a future working day, thus excluding weekends. I would also like to exclude personalized holiday dates, in which case the same thing happens (count ++, I guess).

For example, I would like to exclude these dates: ["2019-11-6", "2019-11-13"] How can I integrate this into the code?

I need this to show a future delivery date on a business day, excluding weekends and some custom dates.

I've read and tested loads of guides, but I haven't found anything that works.

jQuery(function($) {
  var monthNames = ["gennaio", "febbraio", "marzo", "aprile", "maggio", "giugno", "luglio", "agosto", "settembre", "ottobre", "novembre", "dicembre"];
  var dayNames = ["domenica", "lunedì", "martedì", "mercoledì", "giovedì", "venerdì", "sabato"]

  var endDate = "",
    noOfDaysToAdd = 1,
    count = 0;
  var someDate = new Date();
  var numberOfDaysToAdd = noOfDaysToAdd;
  someDate.setDate(someDate.getDate());

  while (count < noOfDaysToAdd) {
    endDate = new Date(someDate.setDate(someDate.getDate() + 1));
    if (endDate.getDay() != 0 && endDate.getDay() != 6) {
      count++;
    }
  }

  $('#Date').html(dayNames[endDate.getDay()] + ' ' + endDate.getDate() + ' ' + monthNames[endDate.getMonth()] + ' ' + endDate.getFullYear());
});

Code (JavaScript):

The code works well for the exclusion of weekends, but I would like help to add customized holiday dates as well.

Thank you very much!

 

After several researches I found the solution and it seems to work perfectly.
Here is the working code for those interested:

jQuery(function($) {
  var monthNames = ["gennaio", "febbraio", "marzo", "aprile", "maggio", "giugno", "luglio", "agosto", "settembre", "ottobre", "novembre", "dicembre"];
  var dayNames = ["domenica", "lunedì", "martedì", "mercoledì", "giovedì", "venerdì", "sabato"];
  var holidays = ["2019, 11, 8", "2019, 11, 11", "2019, 11, 12", "2019, 11, 13", "2019, 11, 14", "2019, 11, 15", "2019, 11, 18"];
  var endDate = "",
    noOfDaysToAdd = 3,
    count = 0;
  var someDate = new Date(new Date().toDateString());
  var numberOfDaysToAdd = noOfDaysToAdd;
  someDate.setDate(someDate.getDate());
  while (count < noOfDaysToAdd) {
    endDate = new Date(someDate.setDate(someDate.getDate() + 1));
    var isHoliday = holidays.find(holiday => endDate.getTime() == new Date(holiday).getTime());
    if (isHoliday) {
      console.log('holiday, skipping');
    } else if (endDate.getDay() != 0 && endDate.getDay() != 6) {
      count++;
    }
  }
$('#Date').html(dayNames[endDate.getDay()] + ' ' + endDate.getDate() + ' ' + monthNames[endDate.getMonth()]);  
});

That got WAY too overcomplicated for it's own good. In particular it's manipulating multiple dates when it only needs ONE to start with and work on.

(function() {
	var
		monthNames = [
			'gennaio', 'febbraio', 'marzo', 'aprile',
			'maggio', 'giugno', 'luglio', 'agosto',
			'settembre', 'ottobre', 'novembre', 'dicembre'
		],
		dayNames = [
			'domenica', 'lunedì', 'martedì', 'mercoledì',
			'giovedì', 'venerdì', 'sabato'
		],
		holidays = [ // D M YYYY
			'8 11 2019', '11 11 2019', '12 11 2019', '13 11 2019',
			'14 11 2019', '15 11 2019', '18 11 2019'
		],
		daysToAdd = 20,
		dayWalker = new Date();
	do {
		var
			day = dayWalker.getDay(),
			date = dayWalker.getDate();
		if (holidays.indexOf(
			date + ' ' + (dayWalker.getMonth() + 1) + ' ' + dayWalker.getFullYear()
		) >= 0) console.log('holiday, skipping');
		else if (day > 0 && day < 6) daysToAdd--;
		dayWalker.setDate(date + 1);
	} while (daysToAdd);
	document.getElementById('Date').textContent =
		dayNames[dayWalker.getDay()] + ' ' +
		dayWalker.getDate() + ' ' +
		monthNames[dayWalker.getMonth()] + ' ' +
		dayWalker.getFullYear();
})();

If you store your holidays as a easy format, just make that format per day and look for it. Yes, IE8/earlier doesn't have Array.indexOf, polyfill that if you need support for browsers we really should stop supporting.

See how I store getDate and getDay in variables? I do this as they're each used more than once. Functions are slower than variables, so it's faster to store a value and re-use it than to constantly call the function.

I also kicked the jQuery mental enfeeblement to the curb. Only thing you can learn from JQ is how NOT to write JavaScript. ESPECIALLY using the slow $().HTML() method that basically calls innerHTML, getting the parser involved and running security risk, when you could just get the ACTUAL element and safely use textContent in a fraction the execution time for little to no extra code.
