JavaScript date.setFullYear() method is used to set year into a date object which is created using Date() constructor.
Syntax:
DateObj.setFullYear(year_Value)
Parameter: This method accepts a single parameter as mentioned above and described below:
Return Value: It returns the new date with the updated year which is set by the setFullYear() method.
Below examples illustrate the JavaScript Date setFullYear() Method:
Note: DateObj is a valid Date object created using Date() constructor in which we want to set the year. More codes for the above method are as follows:
Example 1:
JavaScript
// Here a date has been assigned
// while creating Date object
let dateobj =
new Date('October 13, 1996 05:35:32');
// New year 1992 is being set in above Date
// Object with the help of setFullYear() method
dateobj.setFullYear(1992);
// New year from above Date Object is
// being extracted using getFullYear()
let B = dateobj.getFullYear();
// Printing new year
console.log(B);
Output:
1992
Example 2: If in the Date() constructor we do not give any year, still setFullYear() method set a new year which is given as its parameter.
JavaScript
// Here year has not been assigned
// while creating Date object
let dateobj =
new Date('October 13, 05:35:32');
// new year 1992 is being set in above Date
// Object with the help of setFullYear() method
dateobj.setFullYear(1992);
// New year from above Date Object is
// being extracted using getFullYear()
let B = dateobj.getFullYear();
// Printing new year
console.log(B);
Output:
1992
Example 3: If nothing as a parameter is given in the Date() constructor, still setFullYear() method set year but month and date become current ones. Here in output 2 is the month of March because the month name starts from 0 to 11 i.e, 0 for January and 11 for December, and 30 is the current date.
JavaScript
// Here nothing has been assigned
// while creating Date object
let dateobj = new Date();
// new year 2007 is being set in above Date
// Object with the help of setFullYear() method
dateobj.setFullYear(2007);
// Year from above Date Object is
// being extracted using getFullYear()
let B = dateobj.getFullYear();
// Month from above Date Object is
// being extracted using getMonth()
let C = dateobj.getMonth();
// Date from above Date Object is
// being extracted using getDate()
let D = dateobj.getDate();
// Printing new year
console.log(B);
// Printing current month
console.log(C);
// Printing current date
console.log(D);
Output:
2007 2 30
