The getFullYear() method of {{jsxref("Date")}} instances returns the year for this date according to local time.
Use this method instead of the {{jsxref("Date/getYear", "getYear()")}} method.
{{InteractiveExample("JavaScript Demo: Date.prototype.getFullYear()", "shorter")}}
const moonLanding = new Date("July 20, 69 00:20:18");
console.log(moonLanding.getFullYear());
// Expected output: 1969
Syntax
getFullYear()
Parameters
None.
Return value
An integer representing the year for the given date according to local time. Returns NaN if the date is invalid.
Description
Unlike {{jsxref("Date/getYear", "getYear()")}}, the value returned by getFullYear() is an absolute number. For dates between the years 1000 and 9999, getFullYear() returns a four-digit number, for example, 1995. Use this function to make sure a year is compliant with years after 2000.
Examples
Using getFullYear()
The fullYear variable has value 1995, based on the value of the {{jsxref("Date")}} object xmas95.
const xmas95 = new Date("1995-12-25T23:15:30");
const fullYear = xmas95.getFullYear();
console.log(fullYear); // 1995
