Date.setUTCFullYear()

Sets the year of a date object, according to universal time

The setUTCFullYear() method sets the full year for a specified date according to universal time.

var event = new Date('December 31, 1975 23:15:30 GMT-3:00');

console.log(event.getUTCFullYear());
// expected output: 1976

console.log(event.toUTCString());
// expected output: Thu, 01 Jan 1976 02:15:30 GMT

event.setUTCFullYear(1975);

console.log(event.toUTCString());
// expected output: Wed, 01 Jan 1975 02:15:30 GMT

Syntax

dateObj.setUTCFullYear(yearValue[, monthValue[, dayValue]])

Parameters

yearValueAn integer specifying the numeric value of the year, for example, 1995.

monthValueOptional. An integer between 0 and 11 representing the months January through December.

dayValueOptional. An integer between 1 and 31 representing the day of the month. If you specify the dayValue parameter, you must also specify the monthValue.

Return value

The number of milliseconds between 1 January 1970 00:00:00 UTC and the updated date.

Description

If you do not specify the monthValue and dayValue parameters, the values returned from the getUTCMonth() and getUTCDate() methods are used.

If a parameter you specify is outside of the expected range, setUTCFullYear()attempts to update the other parameters and the date information in the Date object accordingly. For example, if you specify 15 for monthValue, the year is incremented by 1 (yearValue + 1), and 3 is used for the month.

Examples

Using setUTCFullYear()

var theBigDay = new Date();
theBigDay.setUTCFullYear(1997);
