  Age determination is undertaken for nearby early-type (BAF) stars, which
constitute attractive targets for high-contrast debris disk and planet imaging
surveys. Our analysis sequence consists of: acquisition of uvby{\beta}
photometry from catalogs, correction for the effects of extinction,
interpolation of the photometry onto model atmosphere grids from which
atmospheric parameters are determined, and finally, comparison to the
theoretical isochrones from pre-main sequence through post-main sequence
stellar evolution models, accounting for the effects of stellar rotation. We
calibrate and validate our methods at the atmospheric parameter stage by
comparing our results to fundamentally determined Teff and log g values. We
validate and test our methods at the evolutionary model stage by comparing our
results on ages to the accepted ages of several benchmark open clusters (IC
2602, {\alpha} Persei, Pleiades, Hyades). Finally, we apply our methods to
estimate stellar ages for 3493 field stars, including several with directly
imaged exoplanet candidates.
