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:

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.  

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. 

Output: 

42
3
1
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  here 1000 is subtracted because 0 to 999 is 1000.  

Output: 

6
33
