JavaScript Date setFullYear() Method Last Updated : 19 May, 2023 Comments Improve Suggest changes Like Article Like Report 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 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 Supported Browsers: Google ChromeInternet ExplorerMozilla FirefoxOperaSafari We have a complete list of Javascript Date Objects, to check those please go through this Javascript Date Object Complete reference article.
