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

dateObj.setMonth(numMonth[, dateVal]) 

Arguments

dateObj

Required. Any Date object.

numMonth

Required. A numeric value equal to the month.

dateVal

Optional. A numeric value representing the date. If not supplied, the value from a call to the getDate method is used.

Remarks

To set the month value using Universal Coordinated Time (UTC), use the setUTCMonth method.

If the value of numMonth is greater than 11 (January is month 0) or is a negative number, the stored year is modified accordingly. For example, if the stored date is "Jan 5, 1996" and setMonth(14) is called, the date is changed to "Mar 5, 1997."

Example

The following example illustrates the use of the setMonth method.

function SetMonthDemo(newmonth){
   var d, s;               //Declare variables.
   d = new Date();         //Create Date object.
   d.setMonth(newmonth);   //Set month.
   s = "Current setting is ";
   s += d.toLocaleString(); 
   return(s);              //Return new setting.
}
