The purpose of this paper is to study the cosmological evolution of the universe in the framework of dynamical Chern-Simons modified gravity. We take pilgrim dark energy model with Hubble and event horizons in interacting scenario with cold dark matter. For this scenario, we discuss cosmological parameters such as Hubble and equation of state and cosmological plane like and squared speed of sound. It is found that Hubble parameter approaches the ranges (for ) and (74, 74.30) (for ) for Hubble horizon pilgrim dark energy. It implies the ranges (for ) and (73.4, 74) (for ) for event horizon pilgrim dark energy. The equation of state parameter provides consistent ranges with different observational schemes. Also, planes lie in the range (). The squared speed of sound shows stability for all present models in the present scenario. We would like to mention here that our results of various cosmological parameters show consistency with different observational data like Planck, WP, BAO, , SNLS, and WMAP.
