White dwarfs (WDs) have been used as chronometers to age date the solar neighborhood, open clusters, globular clusters, and even the Galactic halo field population. The availability of highly accurate and precise Gaia trigonometric parallaxes along with nearly all-sky, homogenous photometric surveys (SDSS, Pan-STARRS) now allows us to improve the precision in WD ages. We report on the consistency of ages among seven WD+WD binaries, run through BASE-9 individually and in pairs. BASE-9 uses Bayesian analysis to estimate the values for stellar parameters, such as age, distance, and metallicity. We found that using Gaia's parallaxes with binary systems constrains the errors in these estimations, by lowering uncertainties and constraining the ages and distances of the systems.
