Using theoretical evolutionary tracks, masses and ages of the stars in the young stellar cluster NGC 2264 have been determined. This information has been used to obtain various cluster properties, such as the age distribution, the mass distribution and the mass-age correlation. The three clusters NGC 6530, IC 2602 and IC 5146 have also been investigated, but in less detail. These produce similar distribution diagrams to NGC 2264. It is concluded that there exists a large age spread in all the clusters and that the rate of formation of stars increases with time.
