Date.prototype.setUTCFullYear()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The setUTCFullYear()
method of Date
instances changes the year for this date according to universal time.
Try it
Syntax
setUTCFullYear(yearValue)
setUTCFullYear(yearValue, monthValue)
setUTCFullYear(yearValue, monthValue, dateValue)
Parameters
yearValue
-
An integer representing the year. For example, 1995.
monthValue
Optional-
An integer representing the month: 0 for January, 1 for February, and so on.
dateValue
Optional-
An integer between 1 and 31 representing the day of the month. If you specify
dateValue
, you must also specifymonthValue
.
Return value
Changes the Date
object in place, and returns its new timestamp. If a parameter is NaN
(or other values that get coerced to NaN
, such as undefined
), the date is set to Invalid Date and NaN
is returned.
Description
If you do not specify the monthValue
and
dateValue
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()
const theBigDay = new Date();
theBigDay.setUTCFullYear(1997);
