setDate Method

Sets the date of a Date object in the local time zone.

function setDate(numDate : Number)


Required. A numeric value equal to the numeric date.


To set the date value using Coordinated Universal Time (UTC), use the setUTCDate method.

If the value of numDate is greater than the number of days in the month stored in the Date object or is a negative number, the date is set to a date equal to numDate minus the number of days in the stored month. For example, if the stored date is January 5, 1996, and setDate(32) is called, the date changes to February 1, 1996. Negative numbers behave similarly.


The following example illustrates the use of the setDate method.

function SetDateDemo(newdate){
   var d, s;                  //Declare variables.
   d = new Date();            //Create date object.
   d.setDate(newdate);        //Set date to newdate.
   s = "Current setting is ";
   s += d.toLocaleString(); 
   return(s);                 //Return newly set date.
