Proper grammar for (post) wedding invitation?

Dan Lastname and Sarah Lastname would like to invite you to join them for a time of celebration of their October the Ninth Wedding at a reception on Saturday the twenty-fourth of October, two thousand and nine.
can someone (Jeruba mainly ;-)) help me clean this up? the dates specifically…not quite sure how they are supposed to be. To clarify, the wedding will have already happened, it is a “post-wedding” reception. (as in 2 weeks earlier). trying to emphasize the fact that the wedding has already happened and no one was invited.

thanks!
