title: Date.prototype.getFullYear()

---
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")}}
```js interactive-example
const moonLanding = new Date("July 20, 69 00:20:18");
console.log(moonLanding.getFullYear());
// Expected output: 1969
```
## Syntax
```js-nolint
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](/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date#the_epoch_timestamps_and_invalid_date).
## 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`.
```js
const xmas95 = new Date("1995-12-25T23:15:30");
const fullYear = xmas95.getFullYear();
console.log(fullYear); // 1995
```
