Summary

The setYear() method sets the year for a specified date according to local time. Because setYear does not set full years ("year 2000 problem"), it is no longer used and has been replaced by the setFullYear method.

Syntax

dateObj.setYear(yearValue)

Parameters

yearValue
An integer.

Returns

If yearValue is a number between 0 and 99 (inclusive), then the year for dateObj is set to 1900 + yearValue. Otherwise, the year for dateObj is set to yearValue.

Examples

Example: Using setYear

The first two lines set the year to 1996. The third sets the year to 2000.

var theBigDay = new Date();

theBigDay.setYear(96);
theBigDay.setYear(1996);
theBigDay.setYear(2000);
