DESCRIPTION: The ages of stars are notoriously difficult to determine\, esp
 ecially for young stars that are still shrouded in dust or surrounded by d
 iscs. Here\, every Myr matters\, as we try to probe the processes of plane
 t formation and stellar composition build-up. If stellar ages are biased\,
  the knock-on effects for exoplanet characterisation are huge\, affecting 
 not just demographics\, but even the detection probabilities for direct im
 aging searches. I discuss the various challenges in ascertaining the ages 
 of hot\, young stars\, and how stellar population synthesis can help us as
 sess whether common tools like stellar isochrones are leading us astray. I
  will present asteroseismology as an alternative technique capable of achi
 eving better age precision\, which approaches 10% for pre-main-sequence st
 ars\, before wrapping up with a few ideas on where this research can break
  new ground.\nSpeaker: Simon Murphy
