JavaScript | date.setSeconds() Function

The date.setSeconds() is an inbuilt function in JavaScript which is used to set seconds into a Date object which is created using Date() constructor.

Syntax:

DateObj.setSeconds(seconds_Value)

DateObj is a valid Date object created using Date() constructor in which we want to set the second. Value of second is from 0 to 59.

Parameter: Here parameter seconds_Value is the value of second which is used to set in Date() constructor.

Return Value: It returns the new Date with updated second which is set by setSeconds() function.

Below program illustrate the setSeconds() function:

<script> 
// Here a date has been assigned 
// while creating Date object 
var dateobj = new Date('October 13, 1996 05:35:32'); 
  
// new second of 52 is being set in above Date 
// Object with the help of setSeconds() function 
dateobj.setSeconds(52); 
  
// new second from above Date Object is 
// being extracted using getSeconds() 
var B = dateobj.getSeconds(); 
  
// Printing new Second 
document.write(B); 
</script> 

Output:

Errors and Exceptions

Example 1: If in Date() constructor we do not give any second, still setSeconds() function set new second which is given as its parameter.

<script> 
// Here second has not been assigned 
// while creating Date object 
var dateobj = new Date('October 13, 1996'); 
  
// new second of 51 is being set in above Date 
// Object with the help of setSeconds() function 
dateobj.setSeconds(51); 
  
// new second from above Date Object is 
// being extracted using getSeconds() 
var B = dateobj.getSeconds(); 
  
// Printing new Second 
document.write(B); 
</script> 

Output:

Example 2: If nothing as parameter is given in Date() constructor, still setSeconds() function set second but month, year, date etc become current ones.

<script> 
// Here nothing has been assigned 
// while creating Date object 
var dateobj = new Date(); 
  
// new second of 42 is being set in above Date 
// Object with the help of setSeconds() function 
dateobj.setSeconds(42); 
  
// Seconds from above Date Object is 
// being extracted using getSeconds() 
var B = dateobj.getSeconds(); 
  
// month from above Date Object is 
// being extracted using getMonth() 
var C = dateobj.getMonth(); 
  
// date from above Date Object is 
// being extracted using getDate() 
var D = dateobj.getDate(); 
  
// year from above Date Object is 
// being extracted using getFullYear() 
var E = dateobj.getFullYear(); 
  
// Printing new seconds 
document.write(B + "<br>"); 
  
// Printing current month 
document.write(C + "<br>"); 
  
// Printing current date 
document.write(D + "<br>"); 
  
// Printing current year 
document.write(E); 
</script> 

Output:

Here 42 is the new seconds, 3 is the current month i.e April, 1 is the current date and 2018 is the current year.

Example 3: If value of second 66 is given as the parameter of setSeconds() function, It will set 6 as the second because second range is form 0 to 59 and ( 66%60 = 6).

<script> 
// Here date has been assigned 
// while creating Date object 
var dateobj = new Date('October 13, 1996 05:35:32'); 
  
// new second of 66 is being set in above Date 
// Object with the help of setSeconds() function 
dateobj.setSeconds(66); 
  
// seconds from above Date Object is 
// being extracted using getSeconds() 
var B = dateobj.getSeconds(); 
  
// Minute from above Date Object is 
// being extracted using getMinutes() 
var C = dateobj.getMinutes(); 
  
// Printing new seconds 
document.write(B + "<br>"); 
  
// Printing minutes 
document.write(C); 
</script> 

Output:

6
36

Here 6 is the new second and minutes becomes 36 from 35 because second range is form 0 to 59. So when 66 is passed as parameter to the setSeconds() function, it will set the seconds in the respective Date object to (66%60 = 6) and will increment the minutes in the respective Date object by (66/60 = 1).
