exclude holidays and weekends when adding dates in javascript

Question

I would like to add 10 days to a date excluding holidays and weekends. Here is the code i am using but i am unable to figure out how to take out the holidays and weekends. Thanks for any help!!

var someDate = item.INITIAL_REQUEST; 
var numberOfDaysToAdd = 10;
someDate.setDate(someDate.getDate() + numberOfDaysToAdd);
item.FINAL_REQUEST = someDate;

Why not add one day at a time, and check the result to see whether it's a day you want; if not try the next day, and keep track of how many "good" ones you've seen. You're on your own in determining what "holiday" means however. — Pointy, Nov 07 '18 at 20:32
There is also [*DateJS - Do Not Include Weeknds*](https://stackoverflow.com/questions/41517796/datejs-do-not-include-weeknds/41518614#41518614) — RobG, Nov 07 '18 at 22:32

There isn't a built-in command to do this.

Basically you have to add one date at a time, and test each one for whether it's a holiday or weekend. Weekends are easy:

function amIAWeekend(someDate){
  return someDate.getDay() == 6 || someDate.getDay() == 0;
}

Testing for a holiday is much harder. The simplest thing to do might be to have a list of holidays in some sort of JSON format, and then for each date run through the list to see if it matches.

Hope this helps get you started!
