JavaScript Date Functions

Example 1: Display Date and Time on Button Click.

var d = new Date();
document.getElementById("demo").innerHTML = d;
document.getElementById("demo").innerHTML = d.toDateString();

Date and Time can be extract in parts also. Common javascript date and time functions are:

var d = new Date();
document.getElementById("demo").innerHTML = d.getDay();
document.getElementById("demo").innerHTML = d.getFullYear();
document.getElementById("demo").innerHTML = d.getTime();

The setDate() function can be used to add days to a date:
var d = new Date();
d.setDate(d.getDate() + 50);
document.getElementById("demo").innerHTML = d;
