DESCRIPTION:Stars and planets both evolve dramatically during their first 
 several hundred million years\, which has important implications for the s
 ubsequent diversity and habitability of planetary systems. Young stellar a
 ssociations\, open clusters and co-moving groups are fruitful astrophysica
 l laboratories because their members share broad coevality\, composition a
 nd location. Combining information from groups at different ages offers a 
 powerful tool to understand the early evolution of stellar and planetary s
 ystems. Recent photometric surveys have provided key advances in this area
 \, first with the Kepler/K2 mission and now with the Transiting Exoplanet 
 Survey Satellite (TESS) and the Next-Generation Transit Survey (NGTS). I w
 ill discuss various avenues to probe the early evolution of stars and plan
 ets\, beginning with recent successful searches for young transiting plane
 ts\, which also led to serendipitous discoveries of young transiting brown
  dwarfs and eclipsing binaries. I will then present recent work on the ear
 ly evolution of stellar rotation before concluding with a brief look at ho
 w early stellar flare activity might influence subsequent planet habitabil
 ity.
