Evolutionary population synthesis models describing the emitted energy of evolving stellar populations, allow the tracing of galaxy evolution across cosmic time and - in particular - the determination of galaxy stellar ages, which is crucial to astrophysics and cosmology. In this talk I shall focus on two recent results spanning a wide age range for evolving stars in galaxies. Firstly, I shall present the detection of spectral signatures from AGB stars in JWST spectra of teenage massive galaxies 8 Gyr back in cosmic time, which allows the most robust galaxy age determination obtained so far. Jumping to seniority, I shall then show the results of the first modelling of spatially-resolved graveyards in galaxies.
