Why don’t you share the code you’ve written to do this and the issues you’ve run into and perhaps someone can help further?

var stdate = document.getElementById("start").value;
var stdate1=  stdate.split("/");	
var endate = document.getElementById("end").value;
var endate1= endate.split("/");	

for(var i=0; stdate1<endate1; ) {
if( stdate.getDay() >0 && endate.getDay() <6) i++;
stdate.setDate(stdate.getDate()+1) ;

You can use the .getDay() method on the date object.

The date object takes 3 parameters - year, month, day - in that order. You would have to return a date object like this, with the months going from 0 (jan) -11 (dec)

const dateToCheck = new Date(yyyy, mm, dd)

Then with the .getDay() method, you check if it’s a weekend, with sunday === 0 and moving up from there

dateToCheck.getDay() //  0 (sunday) - 6 (saturday)
