<script>
    // Here a date has been assigned
    // while creating Date object
    var A = new Date('October 15, 1996 05:35:32');

    // hour from above is being
    // extracted using getHours()
    var B = A.getHours();

    // Printing hour.
    console.log(B);
</script>

Example 2: If hours are not given, it returns zero (0). It is an exceptional case. 

javascript

<script>
    // Creating a Date object
    var A = new Date('October 12, 1996');

    // extracting hours from the date object
    var B = A.getHours();

javascript

<script>
    // Creating a Date object
    var A = new Date('October 35, 1996 12:35:32');

    var B = A.getHours();

    // Printing hour.
    console.log(B);
</script>

javascript

<script>
    // Creating a Date object
