I think that's maybe a little too early, but I know people do it. At the end of the day do what works for you! I just think the more time you give people, the more they put it off. We sent save the dates about 10 months in advance (believe me, I would have liked to do this earlier, but got push back from FI, FMIL, and my mom - all thought it was way too early and I didn't feel like arguing! Plus FI and his mom really dragged their feet on getting me addresses, so some didn't even go out until a little later), and will send our formal invitations in January. So for our 6.22.13 wedding, we did: Save the dates - 8.2012 (10 months in advance) Formal invitations: 1.2013 (5.5 months in advance) RSVP Date: 3.1.2013 (3.5 months in advance, but our room block is only held until 3.22.13 and I want people to have time to book)
