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 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.

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

console.log(fullYear); // 1995
