Abstract. Young open clusters have always been a platform for star formation studies. Irrespective of the previous assumption that all members in the cluster are coeval, recent studies show the presence of age range in young open clusters. Our study, based on multi-wavelength analysis of clusters younger than 40 Myr tries to identify any episodic formation of stars in young clusters. In this poster we present the results obtained for 5 young clusters; all less than 40 Myr. We used deep field optical UBVRI photometry, spectroscopy, NIR data from 2MASS and Spitzer data at mid and far IR wavelengths. We have looked for episodic star formation in these clusters, giving rise to a range in age for the cluster stars and have attempted to model their star formation history.
