## exclude weekends in javascript date calculation

calculate number of weekends between two dates javascript
javascript date difference in days
javascript date calculations
count holidays between two dates javascript
time difference in javascript

I have two sets of codes that work. Needed help combining them into one.

This code gets me the difference between two dates. works perfectly:

```function test(){
var date1 = new Date(txtbox_1.value);
var date2 = new Date(txtbox_2.value);

var diff = (date2 - date1)/1000;
var diff = Math.abs(Math.floor(diff));

var days = Math.floor(diff/(24*60*60));
var leftSec = diff - days * 24*60*60;

var hrs = Math.floor(leftSec/(60*60));
var leftSec = leftSec - hrs * 60*60;

var min = Math.floor(leftSec/(60));
var leftSec = leftSec - min * 60;

txtbox_3.value = days + "." + hrs; }
```

source for the above code

The code below by @cyberfly appears to have the answer of excluding sat and sun which is what i needed. source. However, its in jquery and the above code is in JS. Therefore, needed help combining as i lacked that knowledge :(

```<script type="text/javascript">

\$("#startdate, #enddate").change(function() {

var d1 = \$("#startdate").val();
var d2 = \$("#enddate").val();

var minutes = 1000*60;
var hours = minutes*60;
var day = hours*24;

var startdate1 = getDateFromFormat(d1, "d-m-y");
var enddate1 = getDateFromFormat(d2, "d-m-y");

var days = calcBusinessDays(new Date(startdate1),new Date(enddate1));

if(days>0)
{ \$("#noofdays").val(days);}
else
{ \$("#noofdays").val(0);}

});

</script>
```

EDIT Made an attempt at combining the codes. here is my sample. getting object expected error.

```function test(){
var date1 = new Date(startdate.value);
var date2 = new Date(enddate.value);
var diff = (date2 - date1)/1000;
var diff = Math.abs(Math.floor(diff));
var days = Math.floor(diff/(24*60*60));
var leftSec = diff - days * 24*60*60;
var hrs = Math.floor(leftSec/(60*60));
var leftSec = leftSec - hrs * 60*60;
var min = Math.floor(leftSec/(60));
var leftSec = leftSec - min * 60;

var startdate1 = getDateFromFormat(startdate, "dd/mm/yyyy hh:mm");
var enddate1 = getDateFromFormat(enddate, "dd/mm/yyyy hh:mm");
noofdays.value = days + "." + hrs; }

start: <input type="text" id="startdate" name="startdate" value="02/03/2015 00:00">
end: <input type="text" id="enddate" name="enddate" value="02/03/2015 00:01">
<input type="text" id="noofdays" name="noofdays" value="">
```

JavaScript support for excluding weekends., JavaScript support for excluding weekends. You'll just need to change add a class called "sdate" to you start date field, a class It does not generate the calculation of the total requested vacation days without weekend. If you’d like to calculate the difference between two dates while excluding weekends and holidays, use the NETWORKDAYS function instead. This also looks for 3 arguments: the start date, the end date, and optional holidays. =NETWORKDAYS(start_date, end_date, [holidays])

Here's a simple function to calculate the number of business days between two date objects. As designed, it does not count the start day, but does count the end day so if you give it a date on a Tuesday of one week and a Tuesday of the next week, it will return 5 business days. This does not account for holidays, but does work properly across daylight savings changes.

```function calcBusinessDays(start, end) {
// This makes no effort to account for holidays
// Counts end day, does not count start day

// make copies we can normalize without changing passed in objects
var start = new Date(start);
var end = new Date(end);

// initial total

// normalize both start and end to beginning of the day
start.setHours(0,0,0,0);
end.setHours(0,0,0,0);

var current = new Date(start);
current.setDate(current.getDate() + 1);
var day;
// loop through each day, checking
while (current <= end) {
day = current.getDay();
if (day >= 1 && day <= 5) {
}
current.setDate(current.getDate() + 1);
}
}
```

And, the jQuery + jQueryUI code for a demo:

```// make both input fields into date pickers
\$("#startDate, #endDate").datepicker();

// process click to calculate the difference between the two days
\$("#calc").click(function(e) {
\$("#startDate").datepicker("getDate"),
\$("#endDate").datepicker("getDate")
);
\$("#diff").html(diff);
});
```

And, here's a simple demo built with the date picker in jQueryUI: http://jsfiddle.net/jfriend00/z1txs10d/

Calculate Days,Exclude Weekends and Holidays Using Javascript , <title>Date</title>. </head>. <script>. var startDate = "01/25/2017", endDate = "01/​27/2017";. var currentYear = (new Date).getFullYear();. var disabledDays  Rama this will just exclude the weekends. But i want something else. suppose there is start date i.e 31st march which is a friday and today is 5th of april so i want result to be 3 as there is 3 working days from friday to wednesday.

@RobG has given an excellent algorithm to separate business days from weekends. I think the only problem is if the starting days is a weekend, Saturday or Sunday, then the no of working days/weekends will one less.

Corrected code is below.

```function dateDifference(start, end) {

// Copy date objects so don't modify originals

var s = new Date(start);
var e = new Date(end);

if( s.getDay() == 0 || s.getDay() == 6 ) {
}

// Set time to midday to avoid dalight 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 Sunday or Saturday, add to business days
if (s.getDay() != 0 && s.getDay() != 6) {
++days;
}
//s.setDate(s.getDate() + 1);
}
}
var weekEndDays = totalDays - days + addOneMoreDay;
return weekEndDays;
}
```

Calculate number of working days - JavaScript, please help me to write code in JS which will calculate no. of working days when start and end date are provided, excluding the weekends. Count Workdays excluding Holidays and Weekends (Saturday & Sunday) The function NETWORKDAYS is used while counting the total number of workdays in Excel. While counting the workdays using this function Saturdays and Sundays are considered as weekends by default. The syntax of this function is, =NETWORKDAYS (start_date, end_date, [holidays]).

First Get the Number of Days in a month

```     totalDays(month, year) {
return new Date(year, month, 0).getDate();
}
```

Then Get No Of Working Days In A Month By removing Saturday and Sunday

```  totalWorkdays() {
var d = new Date(); // to know present date
var m = d.getMonth() + 1; // to know present month
var y = d.getFullYear(); // to knoow present year
var td = this.totalDays(m, y);// to get no of days in a month
for (var i = 1; i <= td; i++) {
var s = new Date(y, m - 1, i);
if (s.getDay() != 0 && s.getDay() != 6) {
this.workDays.push(s.getDate());// working days
}else {
this.totalWeekDays.push(s.getDate());//week days
}
}
this.totalWorkingDays = this.workDays.length;
}
```

excluding weekends from a date script, format('D jS, M'));. However i need the code to exclude weekends, as it is not possible to deliver on a weekend, how would i go about changing  Tip: In the formula, A2 is the start date, B2 is the days you want to add. Now the end date which add 45 business days excluding weekends has been shown. Note: If the calculated result is a 5-digit number, you can format it to date with clicking Home > Number Format > Short Date. See screenshot:

Working with dates (and weekends!) in Javascript - JavaScript, Is it possible to allow for weekends in my calculations!? <script type="text/​javascript"> var d1=new Date(2009,0,20); var d2=new Date(2009,1,5); for(var i=0​; d1<d2; ) { if( d1. return business days return weeks*5+tem; }. Include end date in calculation (1 day is added) Days in Results: Exclude Include only Weekends and public holidays Weekends Public holidays (not in weekends) All days No days Custom Holidays for United States – Washington.

Add days to date while ignoring weekends and holidays, number of business days to a given date and it works beautifully. deliveryWeeks = Math.floor(days / 5); //two days per weekend per week  The problem is I dont know how to calculate a due date that exclude weekends. Basically I need a formula or javascript that can calculate due date with business days only. I have current date, I have number of days for each task, but I dont have a way to exclude weekends for a correct due date.

Calculate the diffrence between two dates, excluding weekends and , I'm using Adobe Pro XI. I did some digging and found a script for calculating the difference between two dates to get the a total count of days. Wha. The Date Calculator adds or subtracts days, weeks, months and years from a given date.

• You're missing the `calcBusinessDays()` function in your post which is the relevant portion of the code.
