Let ⊂ℝ be a periodic time scale in shifts ±. We use a fixed point theorem due to Krasnosel'skiĭ to show that nonlinear delay in dynamic equations of the form Δ()=−()()+()Δ(−(,))Δ−(,)+(,(),(−(,))),∈, has a periodic solution in shifts ±. We extend and unify periodic differential, difference, ℎ-difference, and -difference equations and more by a new periodicity concept on time scales
