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); 

/div>

Output:

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:

// date of the month from above date object 
// is extracted using getDate() 
var B = dateobj.getDate(); 
  
// Printing date of the month 
console.log(B);
