setMonth Method (Windows Scripting - JScript)

 

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

Syntax

dateObj.setMonth(numMonth[, dateVal]) 

Arguments

  • dateObj
    Required. Any Date object.

  • numMonth
    Required. A numeric value equal to the month. The value for January is 0, and other month values follow consecutively.

  • dateVal
    Optional. A numeric value representing the day of the month. If this value is 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."

The setFullYear method can be used to set the year, month, and day of the month.

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.
}
