Ast eroseismology offers a real breakthrough in determining stellar ages\, particularly for older solar-type stars\, and the oscillations detec ted by Kepler have been especially critical because of their quality a nd number. In this talk I will present a framework for understanding t he problem of stellar age estimation\, the limitations encountered wit h conventional (pre-seismology) methods\, how asteroseismology provide s constraints on key physical parameters of stars\, and what limitatio ns still exist in the problem of estimating stellar ages.
