Variability is a defining characteristic of young stellar systems, andoptical variability has been heavily studied to select and characterize thephotospheric properties of young stars. In recent years, multi-epochobservations sampling a wider range of wavelengths and time-scales haverevealed a wealth of time-variable phenomena at work during the star formationprocess. This splinter session was convened to summarize recent progress inproviding improved coverage and understanding of time-variable processes inyoung stars and circumstellar disks. We begin by summarizing results fromseveral multi-epoch Spitzer campaigns, which have demonstrated that many youngstellar objects evidence significant mid-IR variability. While some of thesevariations can be attributed to processes in the stellar photosphere, othersappear to trace short time-scale changes in the circumstellar disk which can besuccessfully modeled with axisymmetric or non-axisymmetric structures. We alsoreview recent studies probing variability at shorter wavelengths that provideevidence for high frequency pulsations associated with accretion outbursts,correlated optical/X-ray variability in Classical T Tauri stars, and magneticreversals in young solar analogs.
