According to Diamond Feng Shui, the Period for your apartment and that of the building are based on when you move in. If you moved in prior to Feb. 2004 and since then the building has been sold or the exterior renovated or painted, the building moved into Period 8 but your apartment remains Period 7 or earlier. If your personal situation is any more complicated than this, it's best to use one of your vouchers to talk with a coach.
