Qrilka, I got a bad date in that example, but it was a different bad date. Maybe this fix will fix it for you too. Anyway, I have moved the code to BitBucket.org, and you can find it at: http://bitbucket.org/mazzarelli/js-date/downloads/ I have implemented Peter’s fix, and fixed another bug in the parsing.

It allows me to do "math" on dates easily. I have enough comments here that I need to get around to implementing/fixing, and maybe when I finally do, I'll include that as an option to reject "rubbish dates". Thanks. Nathan:

If you put in 31/02/2009 (DMY) it changes it to the 3rd of March, which is essentially correct. But it should fail rather than seeming to make up a date. This will happen if you put more days than within a month for any rubbish date. Hi, found a problem. If you put in 31/02/2009 (DMY) it changes it to the 3rd of March, which is essentially correct.

The 50. december does not - as far as I know - exist in any normal calendar. Is it possible to have the function only accept VALID dates? Why is:

MDY

accepted as a valid date? The 50. december does not – as far as I know – exist in any normal calendar. Is it possible to have the function only accept VALID dates?
