setFullYear Method

Sets the year value in the Date object using local time.

function setFullYear(numYear : Number [, numMonth Number [, numDate Number]])


Required. A numeric value equal to the year.
Optional. A numeric value equal to the month. Must be supplied if numDate is supplied.
Optional. A numeric value equal to the date.


All set methods taking optional arguments use the value returned from corresponding get methods, if you do not specify the optional argument. For example, if the numMonth argument is optional, but not specified, JScript uses the value returned from the getMonth method.

In addition, if the value of an argument is greater than its range or is a negative number, other stored values are modified accordingly.

To set the year using Coordinated Universal Time (UTC), use the setUTCFullYear method.

The range of years supported in the date object is approximately 285,616 years from either side of 1970.


The following example illustrates the use of the setFullYear method:

function SetFullYearDemo(newyear){
   var d, s;                 //Declare variables.
   d = new Date();           //Create Date object.
   d.setFullYear(newyear);   //Set year.
   s = "Current setting is ";
   s += d.toLocaleString(); 
   return(s);                //Return new date setting.
