public getUTCMonth() : Number
Returns the month (0 [January] to 11 [December]) of the specified Date object, according to universal time.
Number - An integer.
The following example creates a new Date object and uses Date.getUTCMonth() and Date.getMonth(). The value returned by Date.getUTCMonth() can differ from the value returned by Date.getMonth() if today's date is the first or last day of a month, depending on the relationship between your local time zone and universal time.
var today_date:Date = new Date(); trace(today_date.getMonth()); // output based on local timezone trace(today_date.getUTCMonth()); // output equals getMonth() plus or minus 1
