In this study, we investigate the effects of rotation on four snapshots of the evolution of proto-neutron stars with hyperons and $\\Delta$-resonances in their cores, from birth as neutrino-rich objects to maturity as cold, catalyzed neutron stars. We focus on the effects of uniform rotation on the macroscopic structure of the star at three rotational frequencies -- 346.53 Hz, 716 Hz, and the Kepler frequency.
