Abstract
We study pilgrim dark energy model by taking IR cut-offs as particle and event horizons as well as conformal age of the universe. We derive evolution equations for fractional energy density and equation of state parameters for pilgrim dark energy. The phantom cosmic evolution is established in these scenarios which is well supported by the cosmological parameters such as deceleration parameter, statefinder parameters and phase space of ωϑ and ω ϑ . We conclude that the consistent value of parameter μ is μ<0 in accordance with the current Planck and WMAP9 results.
