JavaScript | date.getMilliseconds() Function

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

Syntax:

DateObj.getMilliseconds()

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

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

Return Values: It returns the millisecond for the given date object. Milliseconds is an integer value ranging from 0 to 999.



Below program illustrate the getMilliseconds() function:

// Here a date has been assigned
// while creating Date object
var DateObj = new Date('October 15, 1996 05:35:32:77');
  
// millisecond from above date object is
// being extracted using getMilliseconds().
var millisec = DateObj.getMilliseconds();
  
// Printing millisecond
console.log(millisec);

Output:

77

Errors and Exceptions:

  • Program 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 05:35:32:77');
      
    // millisecond from above dateobject is
    // being extracted using getMilliseconds().
    var millisec = DateObj.getMilliseconds();
      
    // Printing millisecond
    console.log(millisec);

    Output:

    NaN
  • Program 2: If millisecond is not given, it returns zero (0).
    // Here a date has been assigned
    // while creating Date object
    var DateObj = new Date('October 13, 1996 05:35:32');
      
    // millisecond from above dateobject is being
    // extracted using getMilliseconds()
    var millisec = DateObj.getMilliseconds();
      
    // Printing millisecond
    console.log(millisec);

    Output:

    0
  • Program 3: If nothing as parameter is given to the Date() constructor, it returns current millisecond.
    // Creating a Date Object
    var DateObj = new Date();
      
    // millisecond from above Date object is being
    // extracted using getMilliSeconds()
    var millisec = DateObj.getMilliseconds();
      
    // Printing current millisecond
    console.log(millisec);

    Output:

    279
  • Program 4: If millisecond as 1003 is given while creating the Date object, the function will return 0 as exception because milliseconds range is in between 0 to 999 and 1003 is out of this range.
    // Here a date has been assigned
    // while creating Date object
    var DateObj = new Date('October 13, 1996 05:35:32:1003');
      
    // millisecond from above dateobject is being
    // extracted using getMilliseconds()
    var millisec = DateObj.getMilliseconds();
      
    // Printing millisecond
    console.log(millisec);

    Output:

    0

Application: It has many applications such as getting current millisecond. Below program shows one of the applications of this function. It gives the current millisecond.

// Creating Date Object
var DateObj = new Date();
  
// millisecond from above Date Obect is
// being extracted using getMilliSeconds()
var millisec = DateObj.getMilliseconds();
  
// Printing current millisecond
console.log(millisec);

Output:

79
