Given a date and the task is to determine if the given date is a weekend (In this case we are considering Saturday as the weekend. There are two methods to solve this problem which are discussed below:
Approach 1:
- Use .getDay() method on the Date object to get the day.
- Check if it is 6 or 0 (6 denotes Saturday and 0 denotes Sunday).

<p id="GFG_DOWN">

<script>
var el_up = document.getElementById("GFG_UP");
var el_down = document.getElementById("GFG_DOWN");
var date = new Date();
el_up.innerHTML = "Click on the button to "
+ "check if the given date is Weekend"
+ " or not.<br>Date = " + date;
function gfg_Run() {
var day = date.getDay();
var ans = (day === 6 || day === 0);
if (ans) {
ans = "Today is Weekend.";
} else {
ans = "Today is not Weekend.";
}
el_down.innerHTML = ans;
}
</script>
</body>
</html>

Approach 2:
- Use .toString() method to convert the Date object to string.
- Get the String from the date object using .substring() method.
