setUTCMonth Method (Date) (JavaScript)

Sets the month value in the Date object using Universal Coordinated Time (UTC).

dateObj.setUTCMonth(numMonth[, dateVal])

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 it is not supplied, the value from a call to the getUTCDate method is used.

To set the month value using local time, use the setMonth method.

If the value of numMonth is greater than 11 (January is month 0), or is a negative number, the stored year is incremented or decremented appropriately. For example, if the stored date is "Jan 5, 1996 00:00:00.00", and setUTCMonth(14) is called, the date is changed to "Mar 5, 1997 00:00:00.00."

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

The following example illustrates the use of the setUTCMonth method.

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