Setting the timeline of the events which shaped the Milky Way disc through its 13 billion year old history is one of the major challenges in the theory of galaxy formation. Achieving this goal is possible using late-type stars, which in virtue of their long lifetimes can be regarded as fossil remnants from various epochs of the formation of the Galaxy. I present recent studies on the subject, using both seismic and isochrone ages, and stress the importance of dealing with survey selection functions and target selection effects to derive unbiased inferences in stellar population studies
