JavaScript | date.getDate() Function

The date.getDate() is an inbuilt function in JavaScript which is used to fetch the date of a month from a given Date object.

Syntax:

DateObj.getDate()

In the above syntax, DateObj is a valid Date object created using Date() conctructor from which we want to fetch date.

Parameter: This function does not takes any parameter. It is just used along with a Date Object from which we want to fetch 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.



Below program illustrate the getDate() method:-

// 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
console.log(B);

Output:

13

Errors and Exceptions:

  • Code #1: 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.
    // 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.
    console.log(B);

    Output:

    NaN
  • Code #2: If date of the month is not given, by default it returns 1. It is an exception case.
    // 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
    console.log(B);

    Output:

    1
  • Code #3: If nothing as parameter is given to the Date constructor, then the function returns current date of the month.
    // 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
    console.log(B);

    Output:

    21
