Date.prototype.setFullYear()
The setFullYear()
method sets the full year for a
specified date according to local time. Returns new timestamp.
Syntax
setFullYear(yearValue)
setFullYear(yearValue, monthValue)
setFullYear(yearValue, monthValue, dateValue)
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.
dateValue
-
Optional. An integer between 1 and 31 representing the day of the month. If you specify the
dateValue
parameter, you must also specify themonthValue
.
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
dateValue
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);
