Date.prototype.getFullYear()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The getFullYear() method of Date instances returns the year for this date according to local time.

Use this method instead of the getYear() method.

Try it

const moonLanding = new Date("July 20, 69 00:20:18");

console.log(moonLanding.getFullYear());
// Expected output: 1969

Syntax

js
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 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 Date object xmas95.

js
const xmas95 = new Date("1995-12-25T23:15:30");
const fullYear = xmas95.getFullYear();

console.log(fullYear); // 1995
