Sets the numeric date of the Date object using local time.

The numDate argument is a numeric value equal to the numeric date.

To set the date value using Universal Coordinated 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 have a similar behavior.

The following example illustrates the use of the setDate method:

function SetDateDemo(newdate)
  var d, s;
  d = new Date();
  s = "Current setting is ";
  s += d.toLocaleString();
