A Hanger Accessory Device for keeping track of how many times an article of clothing has been worn since it was last laundered. The Hanger Accessory Device generally includes a housing having an upper end, a lower end, and a receiver opening extending therebetween. The upper portion of the outer surface of the housing includes first markings and the lower portion of the outer surface of the housing includes second markings. By rotating the housing (and thus the outwardly-facing markings) around a stem of a hanger, an individual may keep track of how many times an article of clothing has been worn or used between washings.
