JavaScript Date setUTCMilliseconds() Method
Last Updated :
11 Jul, 2025
The date.setUTCMilliseconds() method is used to set milliseconds according to universal time into a date object which is created using Date() constructor.
Syntax:
DateObj.setUTCMilliseconds(milliseconds_Value);
Parameter: This method accepts a single parameter as mentioned above and described below:
- milliseconds_Value: This parameter holds the value of millisecond which is used to set in Date() constructor.
Return Values: It returns the new i.e. updated millisecond which is set by the setUTCMilliseconds() method.
Note: The DateObj is a valid Date object created using the Date() constructor in which we want to set the millisecond according to universal time. The value of milliseconds is from 0 to 999.
Below are examples of the Date.setUTCMilliseconds() method.
Example 1:
JavaScript
// Here a date has been assigned according to
// universal time while creating Date object
let dateobj =
new Date('October 13, 1996 05:35:32:77 GMT-3:00');
// New millisecond of 52 is being set in above Date
// Object with the help of setUTCMilliseconds() method
dateobj.setUTCMilliseconds(52);
// New millisecond from above Date Object is
// being extracted using getUTCMilliseconds()
let B = dateobj.getUTCMilliseconds();
// Printing new millisecond
console.log(B);
Output:
52
Example 2: If in the Date() constructor we do not give a millisecond while creating the Date object, still setUTCMilliseconds() method will be able to set new millisecond which is given as its parameter in the created Date object.
JavaScript
// Here millisecond has not been assigned according
// to universal time while creating Date object
let dateobj = new Date('October 13, 1996 GMT-3:00');
// New millisecond of 51 is being set in above Date
// Object with the help of setUTCMilliseconds() method
dateobj.setUTCMilliseconds(51);
// New millisecond from above Date Object is
// being extracted using getUTCMilliseconds()
let B = dateobj.getUTCMilliseconds();
// Printing new millisecond
console.log(B);
Output:
51
Example 3: If nothing as a parameter is given in the Date() constructor, still setUTCMilliseconds() method will be able to set milliseconds but a month, year, date, etc remains current according to universal time.
Here 42 is the new milliseconds, 3 is the current month i.e. April, 1 is the current date and 2018 is the current year according to universal time.
JavaScript
// Here nothing has been assigned according
// to universal time while creating Date object
let dateobj = new Date();
// New millisecond of 42 is being set in above Date
// Object with the help of setUTCMilliseconds() method
dateobj.setUTCMilliseconds(42);
// Milliseconds from above Date Object is
// being extracted using getUTCMilliseconds()
let B = dateobj.getUTCMilliseconds();
// Month from above Date Object is
// being extracted using getUTCMonth()
let C = dateobj.getUTCMonth();
// Date from above Date Object is
// being extracted using getDate()
let D = dateobj.getUTCDate();
// Year from above Date Object is
// being extracted using getUTCFullYear()
let E = dateobj.getUTCFullYear();
// Printing new milliseconds
console.log(B);
// Printing current month
console.log(C);
// Printing current date
console.log(D);
// Printing current year
console.log(E);
Output:
42

2018
Example 4: If the value of millisecond 1006 is given as the parameter of the setUTCMilliseconds() method, It will set 6 as the millisecond because the millisecond range is from 0 to 999, and hence 1006-1000=6 here 1000 is subtracted because 0 to 999 is 1000.
JavaScript
// Here date has been assigned according to
// universal time while creating Date object
let dateobj =
new Date('October 13, 1996 05:35:32:45 GMT-3:00');
// New millisecond of 1006 is being set in above Date
// Object with the help of setUTCMilliseconds() method
dateobj.setUTCMilliseconds(1006);
// Milliseconds from above Date Object is
// being extracted using getUTCMilliseconds()
let B = dateobj.getUTCMilliseconds();
// Second from above Date Object is
// being extracted using getUTCSeconds()
let C = dateobj.getUTCSeconds();
// Printing new Milliseconds
console.log(B);
// Printing second
console.log(C);
Output:
6
