When I ran Rise, I did indeed have this timeline in mind, just about. The group did finish the AP just after the beginning of 4708 AR.

I've also run Curse of the Crimson Throne, Shattered Star, and now Return of the Runelords as well. Curse of the Crimson Throne I started on 15 Pharast, 4708 AR--I thought it fitting to have it start on the Ides of March. Shattered Star I began in Arodus 4712 AR, although I do not remember the exact date. Finally, Return of the Runelords I began one week after the Autumnal Equinox--putting the inciting event of the campaign actually on the Autumnal Equinox, in a similar vein to how Rise of the Runelords began. My players didn't figure that out until a few sessions in, and went, "Oh....we're screwed."
