I've also added unit tests to the library, so any changes I may make should be caught before they're delivered out. @Tom,

It should return 0 if startDate is greater by < 24 hrs. -Junaid. Hi Gareth,

In your DateUtils.dateDiff(“date”, startDate, endDate) method, it returns -1 if startDate has a time component > endDate’s time component. It should return 0 if startDate is greater by < 24 hrs.

After doing a little more research, I will be updating this to use the standard (which appears to be documented very well <a href="http://en.wikipedia.org/wiki/ISO_week_date" target="_blank" rel="nofollow">here</a>). Thanks for bringing this to my attention. I'll make an blog update when I've made the changes. Actually, there is a standard for this which I did not know about.

Your implementation for weekOfYear is too simplistic. You can't just divide the day of the year by 7 and return that as the week. A proper implementation would use something like a 'minimal-days-in-first-week' value (which is four in Germany) to figure out when the first week of the year starts, and when the last week ends. For example, the 29-Dec-2008 is in week 01/2009, and the 29-Dec-2009 is in week 53/2009. Note the year difference in the first example.

I read, u updated the code on google, but when i look into the 1.0.4 release, all .as classes are of date 22.12.2008. maybe you find the time to commit your latest version. Hi Gareth,

Glad that they're useful to you. On to your questions: 1. Yup, everything that I've documented is in the google code base (and a few things are in there that I haven't yet blogged on such as Holiday and the DST stuff) 2. Yes, weekOfYear is a little over halfway through DateUtils.as (line 303 according the the "view source" at googlecode). The method accepts a date and returns the week of the year (from 1 to 53). Here's the <a href="/2008/12/flex-date-utils-dayofyear-and-weekofyear/" rel="nofollow">blog post</a> 3. I'm not sure there's a right or a wrong way to do it, but that certainly sounds like a logical method of solving the problem :) You could also perhaps try Date.parse( dateAsString ) on the date, but that can also return null (if the date isn't formatted correctly), so your way seems best.

First, have you updated the Google Code with the latest items posted for the date utilities? Second. When I as looking for the Week of Year, I didn't notice that you already had something in the Date Utilities. Maybe you just added it and hadn't put it on the Google Code. I was wondering if your method handles the issues discussed here (http://www.actionscript.org/forums/showthread.php3?t=65502). I used the code from this forum and converted it to AS3 code to work for my application. Third. I probably didn't do this the right way, but I need to convert a date with a month abbreviation. So, I just modified your code to have an array for abbreviated months and then created a function to get the month number from the abbreviation. Again, thanks for your code. Gareth,

I was just wondering how your DateTime/DST stuff was coming along. Should make for a nice, full-featured package once it's done. Can't wait :) Thanks, Nate.
