JavaScript date.setHours() method is used to set hours into a date object which is created using the Date() constructor.
Syntax:
DateObj.setHours(hours_Value)
Parameter: This method accepts a single parameter as mentioned above and described below:
- hours_Value: This parameter holds the value of hour which is used to set in the Date() constructor.
Return Value: It returns the new date with the updated hour which is set by the setHours() method.
The below examples illustrate the JavaScript Date setHours() Method:
Note: DateObj is a valid Date object created using the Date() constructor in which we want to set the hours. More codes for the above method are as follows:
Example 1: If in the Date() constructor we do not give an hour while creating the Date object, still setHours() method will set the new hour which is given as its parameter.
javascript
let dateobj = new Date( 'October 13, 1996' );
dateobj.setHours(11);
let B = dateobj.getHours();
console.log(B);
|
Output:
11
Example 2: If nothing as a parameter is given in the Date() constructor, still setHours() method set hour but a month, year and date will be a current month, year, and date. Here 11 is the new hour, 2 is the current month i.e March, 30 is the current date and 2018 is the current year.
javascript
let dateobj = new Date();
dateobj.setHours(11);
let B = dateobj.getHours();
let C = dateobj.getMonth();
let D = dateobj.getDate();
let E = dateobj.getFullYear();
console.log(B);
console.log(C);
console.log(D);
console.log(E);
|
Output:
11
2
30
2018
Example 3: If the value of an hour as 26 is given in the parameter of setHours() method, It will set 2 as the hour because the hour range is from 0 to 23 and. Here 2 is the new hour, 9 is the month i.e October, 14 is the date and the year is 1996. Here as we see that 13 was the original date but the output becomes 14 because 26 hours given as the parameter of the method converted to 2 hours of the next day that is why the date incremented by 1 i.e, from 13 to 14.
javascript
let dateobj =
new Date( 'October 13, 1996 05:35:32' );
dateobj.setHours(26);
let B = dateobj.getHours();
let C = dateobj.getMonth();
let D = dateobj.getDate();
let E = dateobj.getFullYear();
console.log(B);
console.log(C);
console.log(D);
console.log(E);
|
Output:
2
9
14
1996
