What is the star-formation history of the Milky Way? How old are Galactic halo and thick disk stars? Traditional age-dating of stars relies on clusters, which only offer a limited view of these stellar populations. I will show that white dwarf stars offer a way forward. Specifically, I will show how optical and near-IR photometry, Gaia astrometry, and a Bayesian modeling approach allows us to determine precision ages for individual white dwarfs and derive population ages.
