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:
- year_Value: This parameter holds the value of year which is used to set in the Date() constructor.
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 objectlet dateobj =new Date('October 13, 1996 05:35:32');// New year 1992 is being set in above Date// Object with the help of setFullYear() methoddateobj.setFullYear(1992);// New year from above Date Object is// being extracted using getFullYear()let B = dateobj.getFullYear();// Printing new yearconsole.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 objectlet dateobj =new Date('October 13, 05:35:32');// new year 1992 is being set in above Date// Object with the help of setFullYear() methoddateobj.setFullYear(1992);// New year from above Date Object is// being extracted using getFullYear()let B = dateobj.getFullYear();// Printing new yearconsole.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 objectlet dateobj = new Date();// new year 2007 is being set in above Date// Object with the help of setFullYear() methoddateobj.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 yearconsole.log(B);// Printing current monthconsole.log(C);// Printing current dateconsole.log(D); |
Output:
2007 2 30
