The setFullYear() method of Date instances changes the year, month, and/or day of month for this date according to local time.
Date.prototype.setFullYear()
Try it
Syntax
js
setFullYear(yearValue)
setFullYear(yearValue, monthValue)
setFullYear(yearValue, monthValue, dateValue)
Parameters
-
yearValue -
An integer representing the year. For example, 1995.
monthValueOptional-
An integer representing the month: 0 for January, 1 for February, and so on.
dateValueOptional-
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 same values as what are returned by getMonth() and getDate() are used.
If a parameter you specify is outside of the expected range, other parameters and the date information in the Date object are updated 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()
js
const theBigDay = new Date();
theBigDay.setFullYear(1997);
