Master light curves for the blazars BL Lac and OJ287 are analyzed for periodicities longer than 30 days using a method described in an earlier paper. In BL Lac, a long-term trend described by a harmonic with P = 34 yr and A = 0.7 mJy is observed, as well as a periodic component with P = 7.8 yr and A = 0.6 mJy. The light curve for OJ287 shows a long-period component with P ∼ 11 yr and A ∼ 8 mJy. In neither of these two objects were there significant periodic components with P < 7 yr.
