Javascript date field utility

I need to do date validation for international date formats. The utility should pass following date formats

12 November 2009
12-november-2009
12-nov-2009
12-novembber-2009

Note that the last one has spelling error. However one need开发者_运维百科s to look at only three letters 'nov' to identify that it is November. I was wondering it there is a JavaScript date helper utility out there for me to get started with.

Try DateJS library, but for spelling error, I think it can't help it.
