setUTCDate Method

Sets the numeric day of the month in the Date object using Coordinated Universal Time (UTC).

function setUTCDate(numDate : Number)


Required. A numeric value that is equal to the day of the month.

To set the day of the month using local time, use the setDate 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 setUTCDate(32) is called, the date changes to February 1, 1996. Negative numbers have a similar behavior.

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

The following example illustrates the use of the setUTCDate method.

function SetUTCDateDemo(newdayofmonth){
    var d = new Date();
    // Set UTC day of month.

    var s = d.toUTCString();
