Hey geek! The constant emerging technologies in the world of web development always keeps the excitement for this subject through the roof. But before you tackle the big projects, we suggest you start by learning the basics. Kickstart your web development journey by learning JS concepts with our JavaScript Course.

Example:

javascript

<script>
  // Here a date has been assigned
  // while creating Date object
  var dateobj = new Date('October 13, 1996 05:35:32');
 
  // date of the month from above Date Object is
  // being extracted using getDate()
  var B = dateobj.getDate();
 
  // Printing date of the month
  document.write(B);
</script>

Output:

The date.getDate() method is used to fetch the date of a month from a given Date object.
Syntax:

DateObj.getDate()

Parameter: This method does not takes any parameter. It is just used along with a Date Object from which we want to fetch the date of the month.
Return values: It returns the date of the month for the given date.The date of the month is an integer value ranging from 1 to 31.
Note: The DateObj is a valid Date object created using Date() conctructor from which we want to fetch date.
More codes for the above method are as follows:
Example1: The date of the month should must lie in between 1 to 31 because none of the month have date greater than 31 that is why it returns NaN i.e, not a number because date for the month does not exist.

javascript

<script>
  // Here a date has been assigned
  // while creating Date object
  var dateobj = new Date('October 33, 1996 05:35:32');
 
  // date of the month given above date object
  // is being extracted using getDate().
  var B = dateobj.getDate();
 
  // Printing date of the month.
  document.write(B);
</script>

Output:

NaN

Example 2: If date of the month is not given, by default it returns 1. It is an exception case.

javascript

<script>
  // Here a date has been assigned
  // while creating Date object
  var dateobj = new Date('October 1996 05:35:32');
 
  // date of the month from above date object
  // is extracted using getDate()
  var B = dateobj.getDate();
 
  // Printing date of the month
  document.write(B);
</script>

Output:

Example 3: If nothing as parameter is given to the Date constructor, then the function returns current date of the month.

javascript

<script>
  // Creating Date Object
  var dateobj = new Date();
 
  // date of the month from above object
  // is being extracted using getDate().
  var B = dateobj.getDate();
  
  // Printing current date
  document.write(B);
</script>
