Date.prototype.setUTCFullYear()
The setUTCFullYear()
method sets the full year for a specified date according to universal time.
Syntax
<var>dateObj</var>.setUTCFullYear(<var>yearValue</var>[, <var>monthValue</var>[, <var>dayValue</var>]])
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 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 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);
