Reading the newsgroup FAQ with care should help you, provided that the
version you choose is not too recent.

Since new Date() accepts both "13/11/2008" and "11/13/2008", one
cannot rely solely on new Date() . Indeed, even if you try all
browsers that you have, you still cannot rely on it, as date string
formats are not specified in ISO/IEC 16262.

You will, therefore, need to know something about the possible formats
that you may encounter - for example, will the month always be a word
rather than a number? May it be abbreviated? How much?

XP sp2 IE6 accepts new Date("Ju 30th, 2008") giving July 30th.

It's a good idea to read the newsgroup c.l.j and its FAQ. See below.
