Determining the precise age of stars, though challenging, has far-reaching impacts. Accurate stellar age determinations are pivotal for understanding our Galaxy's chemical evolution, and for refining our understanding of protoplanetary disc formation and evolution, where precise ages are particularly important due to the rapid disc evolution timescales. Stellar ages cannot be obtained from direct measurements; they can only be estimated or inferred. Asteroseismology -- the study of stellar pulsations -- is one of the most promising techniques for inferring stellar ages. Its underlying accuracy is deeply reliant on theoretical stellar models, yet the uncertainties associated with these models are poorly characterised. This work deals with characterising and quantifying systematic (modelling) uncertainties and applying those models to infer the ages of star clusters like the Pleiades.
