How to get the date of the next Saturday?

Question

JavaScript

How to get the date of the nearest future Saturday? That is, for example, the user logged in today and I need to determine that the date is the next Saturday 15.12.

Answer 1

function getDateOfNearestDay(day, date = new Date()) {
  return new Date(date.getFullYear(), date.getMonth(), date.getDate() + ((7 + day - date.getDay()) % 7));
}

const dateOfNearestSaturday = getDateOfNearestDay(6);

Answer 2

function getSaturday() {
    var today = new Date().getUTCDay();
    var diff = 6 - today;
    if ([-1, 0].includes(Math.sign(diff))) {
        return new Date(new Date().setUTCDate(13 - today));
    }
    return new Date(new Date().setUTCDate(diff));
}

Answer 3

const getSaturday = () => {
  let daysUntil = 6 - new Date().getDay(),
       date = new Date().toLocaleDateString().split("-");

  date[2] = parseInt(date[2]) + daysUntil;
  
  return date.join("-"); 		
}
