Per the girls on the Invites & Paper board, the save the dates normally go out 6 to 9 months prior and the wedding invitations normally go out 6 to 8 weeks prior to your wedding date...rsvp dates would depend on when your venue needs a final headcount, but they say you should ask to receive replies from 2 to 3 weeks prior to the wedding date...hope this helps (I know it helps me b/c I was clueless on it all, lol)
