date.setFullYear

The setFullYear() method sets the full year for a specified date according to local time. Returns new timestamp.

Syntax

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

Parameters

yearValue

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

monthValue

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

dayValue

Optional. 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 getMonth() and getDate() methods are used.

If a parameter you specify is outside of the expected range, setFullYear() 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 setFullYear()

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