I wrote a simple .Net program to Check SSL Expiration Date (ssl expiry date) of any remote web site (url).
You can download it from here (only 10kb zipped):
Of course, this being a .Net code, you’d need a FrameWork installed to run it.
Well, run it, if it hangs, install FrameWork (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=0856eacb-4362-4b0d-8edd-aab15c5e04f5&displaylang=en) and then run it again.
