I would not guarantee results if you set values that are out of range. ________________________________

Hi, all; I'm working on making an app that will allow users to navigate from one month to the next based on a start date and end date. I noticed some interesting effects with the date object and days that fall outside the 1-31 range (http://tinyurl.com/5qc46j <http://tinyurl.com/5qc46j> ), so I thought I'd try something similar with months. What I find is if the current month is 11 and you add 1 to it, you'll actually wind up with a date that's not in the _next_ year, but one in the year following. Here's my code public function makeDisplayedMonths(beginDate:Date, endDate:Date):void { var today:Date= new Date(); //set up date for loop var parseDate:Date = beginDate; //equalize parsedate and enddate parseDate.setDate(1); endDate.setDate(1); while (parseDate <= endDate) { //update date parseDate.setMonth(++parseDate.month); trace(parseDate, endDate); } } the trace is this Tue Jul 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009 Fri Aug 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009 Mon Sep 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009 Wed Oct 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009 Sat Nov 1 00:00:00 GMT-0500 2008 Thu Jan 1 00:00:00 GMT-0600 2009 Mon Dec 1 00:00:00 GMT-0600 2008 Thu Jan 1 00:00:00 GMT-0600 2009 Fri Jan 1 00:00:00 GMT-0600 2010 Thu Jan 1 00:00:00 GMT-0600 2009 Note that it goes from Dec 1 2008 to Jan 1 2010, skipping 2009 altogether. Obviously now I know this I can code around it, but it seems like it should either throw an error that the month is out of range or just keep incrementing. Or have I missed something here? Thanks; Amy
