I am working on a code that calculates the total number of days excluding weekends and specified holidays. After researching on various platforms like stackoverflow and adobe forum, I have come up with the following code.
If a public holiday falls on a working day (Saturday-Wednesday), it is excluded from the calculation. However, my issue arises when a public holiday falls on a weekend (Thursday-Friday), as it deducts both the holiday and the weekend days. For example, for a leave duration from 18/09/2018 to 22/09/2018, the total count shows 2 days instead of 3. Similarly, for dates 17/10/2018-21/10/2018, the total count is 1 day instead of 3 days.
I would greatly appreciate any assistance or ideas to resolve this problem!

//Thursday and Friday will be excluded as weekend.
var start = this.getField("From").value;
// get the start date value
var end = this.getField("To").value;
var end = util.scand("dd/mm/yyyy H:MM:SS", end + " 0:00:00");
var start =util.scand("dd/mm/yyyy H:MM:SS", start + " 0:00:00");
event.value = dateDifference(start, end);
function dateDifference(start, end) {
// Copy date objects so don't modify originals
var s = new Date(+start);
var e = new Date(+end);
// Set time to midday to avoid daylight saving and browser quirks
s.setHours(12,0,0,0);
e.setHours(12,0,0,0);
// Get the difference in whole days
var totalDays = Math.round((e - s) / 8.64e7);
// Get the difference in whole weeks
var wholeWeeks = totalDays / 7 | 0;
// Estimate business days as number of whole weeks * 5
var days = wholeWeeks * 5;
// If not even number of weeks, calc remaining weekend days
if (totalDays % 7) {
s.setDate(s.getDate() + wholeWeeks * 7);
while (s < e) {
s.setDate(s.getDate() + 1);
// If day isn't a Thursday or Friday, add to business days
if (s.getDay() != 4 && s.getDay() != 5) {
++days;
}
}
