In this work, the variational iteration method is used for analytic treatment of differential equations with piecewise constant arguments of alternately advanced and retarded type. In order to prove the precision of the results, some comparisons are also made between the exact solutions and the results of the numerical method and the variational iteration method. The obtained results reveal that the method is very effective and convenient for constructing differential equations with piecewise constant arguments.
