In connection with the incompatibility between cluster and Hubble ages, and between the spread in cluster ages and formation during gravitational collapse of the Galaxy, a study of dating based on stellar evolution was conducted. A general approach was developed for estimating isochronal parameters using a statistic which measures the overall coincidence between an isochrone and stars in a color-magnitude diagram. Only the main sequence and lower subgiant branch are analyzed. Attention is given to previous results and methods for cluster age dating, parameterized model isochrones, statistical fitting procedures, an analysis of simulated clusters, and an analysis of observed clusters.
